Best Free Image Compressors and Resizers in 2026
Short answer: TinyPNG is the best free image compressor, with up to 20 images per session at 5MB each on its web tool and 500 free API compressions a month, then $0.009 each. Adobe Express is the best free tool that both compresses and resizes, accepting files up to 40MB with no credit card. Fotor is the pick for batch resizing, with up to 50 images at once and no registration. Kraken's free web tool stops at 1MB per file, so it only fits small images.
Eight tools compared on file size caps, batch sizes, monthly quotas and whether resizing is free, checked on vendor pages in October 2026.
TinyPNG is the best free image compressor, and Adobe Express is the best free tool that both compresses and resizes. This guide ranks eight tools on what their free plans allow: TinyPNG's web tool takes 20 images per session at 5MB each, Adobe Express's resize tool accepts files up to 40MB with no credit card, and Kraken's free web interface stops at 1MB per file. Most searches for a free image compressor come from one of two problems. The photo is too heavy for a website or an upload form, or it has the wrong pixel dimensions for the platform asking for it. Many tools claim to fix both, but the free tier usually limits one of them, so this comparison looks at the size of each file, how many images fit in one batch, any monthly quota, and whether resizing is included at all.
Toolradar data: of the 168 image editing tools we track, 67%% offer a free or freemium door (34 free, 78 freemium), while 33%% (56 tools) have no free tier at all. That leaves a short list of tools whose free plans can handle real work.
Methodology: every limit below was read on the vendor's own pricing, product or help pages, checked in October 2026, not on review sites. Prices are in US dollars. Tools were ranked on what their free plan does for a buyer with this exact problem, then on their cheapest paid step. Tools whose free limits could not be confirmed on their own site were left out.

Anyone compressing a batch of web images who wants the most generous free compression limits and does not need resizing.
- Pro: The free web tool takes up to 20 images at once, each up to 5MB, and converts up to 3 images per session.
- Pro: The Developer API includes 500 free compressions a month with no payment method, then charges $0.009 per compression for the next 9,500.
- Pro: It compresses AVIF, WebP, PNG and JPEG, and it converts HEIC uploads to JPG automatically.
- Con: Resizing is an API feature only, so the free web tool cannot change pixel dimensions.
- Con: The per-session count means a 200-image job takes ten sessions on the free web tool, which drags on a large catalog.
TinyPNG offers a fair and generous free tier, allowing users to compress a significant number of images without cost.
Watch out
5MB image limit can be restrictive
Non-developers who need to resize and compress the same photo for a social post, a banner or an upload form.
- Pro: The free resize tool accepts files up to 40MB and says it compresses to any size you choose.
- Pro: No credit card is required, and the free plan includes 5GB of cloud storage and 10 days of version history.
- Pro: Premium is $9.99 a month with no annual commitment, so you can pay for a single month and stop.
- Con: Its pages disagree on formats: the upload notice accepts WebP, but the resize FAQ lists only JPG and PNG.
- Con: Watermarks and export settings on the free plan are not described on the resize page, so test a download before using it on client work.
Adobe Express offers a generous Free tier, making it accessible for basic creative needs.
Watch out
Generative credit overage fees
Anyone resizing a batch of product or social images to fixed dimensions without creating an account.
- Pro: The resize tool processes up to 50 images at once and needs no registration, according to its own page.
- Pro: It accepts JPG, JPEG, PNG, HEIF, HEIC and WebP, which covers most phone photos and screenshots.
- Pro: Fotor's free plan says edited photos export without watermarks, and its free tier includes 512MB of cloud storage.
- Con: The resize page gives no maximum file size, so a large camera original cannot be confirmed to fit from the vendor page.
- Con: The Pro plan shows no USD amount on its pricing page, so the paid step cannot be quoted in dollars from that source.
Fotor's pricing structure is generally fair, offering a robust free tier for basic users.
Site owners who compress a steady stream of small images and can stay under 20MB a month.
- Pro: The free plan gives 20MB a month, which the pricing page puts at about 200 images.
- Pro: The Growth plan adds 500MB a month for $5.99 a month, or $4.99 a month billed yearly.
- Pro: The Infinite plan costs $11.99 a month, or $9.99 a month billed yearly.
- Con: The free plan caps each upload at 2MB, which rules out most camera originals unless you resize them first.

Imagify's pricing is quite generous, especially with its "infinite" plan at $11.99/month for truly unlimited usage.
Small image sets under 1MB each, where the free web interface is enough and a paid plan covers anything bigger.
- Pro: The free web interface compresses files in batches of up to 20 at a time.

What a free image compressor and resizer does
Compression and resizing solve different problems, and free plans usually limit one of them. A compressor re-encodes the file so it takes fewer bytes, typically with lossy encoding for JPEG, WebP and AVIF, and it leaves the pixel count alone. A resizer changes the pixel dimensions, which is what a platform checks when it asks for a banner at a fixed width and height.
A file can pass one check and fail the other. A photo can be small in megabytes and still the wrong width, or the right width and too heavy for an upload form. That is why this guide measures both jobs, and why a tool that does only one of them on its free plan ranks lower than one that does both.
Why the limit you hit matters more than the price
The limit that matters is the one that stops your job. TinyPNG's free web tool stops at 20 images per session and 5MB per image. Kraken's free web interface rejects any file over 1MB. Imagify's free plan allows 20MB a month, which its pricing page puts at about 200 images, and each upload is capped at 2MB. A blog post with ten hero images at about 3MB each fits TinyPNG's web tool, but not Kraken's, and not Imagify's per-image cap either.
None of the free plans checked here sets a daily cap. Limits come as a count per session (TinyPNG's web tool), a monthly quota (Imagify, and the 500 free compressions a month on TinyPNG's API), or a size per file (Kraken, Imagify, TinyPNG and Adobe Express). A per-session count is a scheduling problem, a monthly quota is a budget problem, and a per-file cap is a preparation problem you solve before you upload.
Key Features to Look For
Per-file size cap (Essential)
Kraken's free web interface stops at 1MB per file. TinyPNG's free web tool accepts up to 5MB per image, Imagify's free plan caps each upload at 2MB, and Adobe Express's resize tool accepts files up to 40MB. Fotor's resize page does not publish a maximum.
Monthly quota (Essential)
Imagify's free plan gives 20MB a month. TinyPNG's Developer API includes 500 free compressions a month and asks for no payment method. A monthly quota is the limit that runs out quietly, so it needs a calendar check.
Resizing on the free plan (Essential)
Adobe Express and Fotor include a free resize tool. Photopea resizes inside a full browser editor. Kraken keeps resizing in its PRO web interface, and TinyPNG's resizing is an API feature rather than part of its web tool.
Sign-up and card requirements (Important)
Fotor says its resize tool needs no registration. Adobe Express says no credit card is required, which is a different promise from no account. TinyPNG's 500 free API compressions need an API key, but no payment method.
Before you pick a free tool
Check the largest original first. A 3MB file fails Kraken's free web interface, which takes only 1MB, but passes TinyPNG's 5MB per-image limit and Adobe Express's 40MB resize cap.
Count the batch before you start. TinyPNG's web tool takes 20 images per session, so a 200-image job takes ten sessions, while Fotor's resize tool takes up to 50 at once.
Decide whether the job needs resizing, compression, or both in one step. Adobe Express and Fotor offer a free resize step on their own pages, while TinyPNG's resizing sits behind its API, so compare TinyPNG alternatives if you need one tool for both.
Read the upload rules on the page you will actually use. Adobe Express's upload notice and its FAQ disagree on formats, so the first page you read may not match the tool.
Evaluation Checklist
Test the largest original against each cap. Kraken's free web interface stops at 1MB per file, while Adobe Express's resize tool accepts files up to 40MB.
Confirm the format list against your files. Fotor accepts HEIC and HEIF, TinyPNG's web tool lists AVIF, WebP, PNG and JPEG, and Adobe Express's resize FAQ names only JPG and PNG.
Download one test file before you commit client work. Not every vendor page states its watermark rule, so the exported file is the only proof for your own use.

Mistakes to Avoid
- ×
Sending a 3MB photo to Kraken's free web interface, which rejects anything over 1MB, and assuming the tool is broken rather than capped.
- ×
Expecting resizing from a free compressor. TinyPNG's web tool compresses and converts, and its resizing sits in the API.
- ×
Planning around a daily allowance. None of the verified free plans sets a daily cap, so the risk is a per-session count or a monthly quota.
- ×
Uploading unreleased client files to a cloud tool without reading its retention rule. TinyPNG states a maximum 48-hour retention, while Squoosh processes files on your own device.
Expert Tips
- →
Resize first when a file is over a cap, then compress. Fotor or Adobe Express can bring a large original down to the dimensions a platform asks for, and the compressor then works on a smaller file.
- →
Use TinyPNG's API for automated jobs. The 500 free compressions a month cover a small site, and the per-compression rate after that is a predictable cost per image.
- →
Check HEIC handling before a phone batch. TinyPNG converts HEIC uploads to JPG automatically, while Fotor accepts HEIC and HEIF files directly.
Red Flags to Watch For
-
A free tier that states no size or count limit anywhere on the vendor's own site. A tool that states no limit should be tested with your largest file before you rely on it.
-
A resize feature that sits only in a paid tier. Kraken keeps resizing in its PRO web interface, so a free compression run cannot change dimensions.
-
A quota measured in megabytes instead of images. Imagify's free 20MB a month is about 200 images only if the files average around 100KB, and a few large originals can use up the quota quickly.
The Bottom Line
Pick TinyPNG when compression is the job: 20 images per session on the free web tool, then 500 free API compressions a month. Pick Adobe Express when one free tool has to resize and compress, with files up to 40MB and no credit card. Pick Fotor for batch resizing of up to 50 images with no registration. Kraken is the right choice only for files under 1MB, and Squoosh suits private, one-off compression in the browser.
Pixlr and Photopea round out the list for people who need an editor, where resizing sits inside a full tool rather than a single-purpose compressor. Limits and prices were checked on vendor pages in October 2026, against the 168 tools in the image editing category.

Frequently Asked Questions
What is the best free image compressor in 2026?
TinyPNG is the best free image compressor on this list. Its free web tool takes up to 20 images per session at 5MB each, and its Developer API includes 500 free compressions a month before charging per use.
Adobe Express is the better pick if the same tool also has to resize, because its free resize tool accepts files up to 40MB with no credit card required.
Is there a free image resizer with no watermark?
Fotor says its free plan lets you export edited photos without watermarks, and its resize tool needs no registration and takes up to 50 images at once. Adobe Express's resize page does not mention watermarks at all, so test a download before using it on client work.
None of the other tools on this list state a watermark rule on the vendor pages checked for this guide.
How much does a free image compressor cost after the free limit?
On TinyPNG's API, the first 500 compressions a month are free, the next 9,500 cost $0.009 each, and the rate drops after that. Imagify's Growth plan adds 500MB of monthly quota, and it costs less per month when billed yearly.
Kraken's Micro plan costs $5 a month or $50 a year for a 500MB monthly image quota, which makes it the cheaper of the two 500MB quotas on this list for steady volume.
What is the file size limit on a free image compressor?
Kraken's free web interface stops at 1MB per file, and Imagify's free plan caps each upload at 2MB. TinyPNG's free web tool accepts up to 5MB per image, and Adobe Express's resize tool accepts up to 40MB.
Fotor's resize page does not publish a maximum, so a large camera original should be tested before a batch job.
Do any free image compressors have a daily limit?
None of the free plans verified for this guide sets a daily cap. The limits are per session on TinyPNG's web tool (20 images), per month on Imagify (20MB) and on TinyPNG's API (500 compressions), or per file on Kraken (1MB).
The practical effect is that a large batch can hit a session or monthly limit quickly, even though no tool counts by the day.
