Free image compressor with no size cap and no signup
Picture too big to attach or upload? Pick a quality, or type the size it has to fit under, and download it. No watermark, no account, no upgrade prompt. Nothing is uploaded, so there is no cap to hit.
No cap on the file
There is no server bill to protect here, so the only limit is your own device, not a plan tier.
No signup, no watermark
No account, no trial, no upgrade prompt on the download. Ads pay for the site.
Nothing is uploaded
That is why there is no cap and no account. Turn your network off once it starts and it still finishes.
Fits under the limit
Type a size in MB and quality drops only as far as it has to in order to fit under it.
How it works
- Pick a quality: High, Balanced, or Small.
- Optional: open the size limit and type the size the file has to fit under, in MB.
- Drop your picture, or click the box to choose a file.
- Download the result. The name ends with a short tag, like
photo-8f2a1c.webp.
Quality or a size limit
The three presets are about how much of the picture to keep. High barely touches it, Small makes the file as light as it can. That is enough most of the time, and the file lands wherever it lands.
A size limit is for when a form refuses anything over a number: 2 MB for an upload, 500 KB for a forum avatar. Type it in and the quality is walked down only as far as it has to go to get under it. If even the lowest usable quality cannot get there, you are told, rather than handed a ruined picture.
The pixel width and height never change. Cropping and resizing are a different job, and this tool does not do them.
Frequently asked questions
Is there a file size limit?
There is no fixed cap, because there is no upload. The practical limit is your device’s memory; a very large picture on a low-memory phone can fail.
Does it add a watermark or need an account?
No watermark, no account, no trial, and no upgrade prompt on the download. The site is free and paid for by ads.
Is my picture uploaded to a server?
No. The work happens on your own device. You can switch your network off after it starts and it will still finish.
Why does my PNG come back as a WebP?
A PNG saved again as a PNG barely gets smaller, so it would not be a compressor. WebP has a quality dial and still holds transparency, so a PNG is saved as WebP and see-through areas stay see-through. If you need the file to stay a PNG, use the image converter instead.
Will it change the size of the picture on screen?
No. The width and height in pixels stay exactly as they were. Only the file gets smaller.
Which formats can I drop in?
JPG, PNG, WebP and AVIF. JPG, WebP and AVIF come back in the same format; PNG comes back as WebP.
