Compress an image
Make the file smaller — by quality, by dimensions, or to an exact target size like 500 KB. Crop, rotate, annotate and download, all without the picture leaving your browser.

Compress an image — smaller file, same picture
Compress shrinks an image file in your own browser. Choose a format and a quality and
watch the size fall in real time, resize it to the dimensions you actually need, or name
a target such as 500 KB and let the tool search for the setting that lands
just under it. Along the way you can crop, rotate, draw on the picture, hide anything
private and add text — then download the result.
How it works
- Open an image. Drag one in, paste it, or pick a file. It is decoded on this device; nothing is uploaded.
- Choose how small. Pick a format, drag the quality slider, and resize if the picture is larger than it needs to be. The panel shows the original size, the new size and the percentage saved, recalculated from a real encode rather than an estimate — so the number you see is the number of bytes you get. Or type a target size and press Hit it.
- Check what you traded. Turn on compare and drag the divider across the picture to see the compressed result against the original at any zoom.
- Edit if you want to. Crop, rotate, draw shapes, arrows and numbered steps, blur or block out anything private, and add text notes. None of it is baked in until you download, so you can go back and change any of it.
- Download. One file, straight to your device.
Frequently asked questions
Are my images uploaded anywhere?
No. Images are decoded in the page and compressed by your own browser. The file
contains no fetch, XMLHttpRequest, WebSocket or
sendBeacon call and no third-party script, so there is nothing to send data
with. It works with the network disconnected entirely.
How much smaller will my image get?
A typical phone photo drops from around 4 MB to under 400 KB at quality 80 with no difference most people can see. The biggest lever is not quality but size in pixels: a 4000-pixel-wide photo shown 1000 pixels wide on a web page carries sixteen times more pixels than it needs. Resize first, then lower quality until you can just start to see it, then step back one notch.
How do I compress an image to exactly 100 KB, 500 KB or 1 MB?
Type the number into Target file size, choose KB or MB, and press Hit it. The tool looks for the highest quality that still fits under your number, and only starts reducing the dimensions if quality alone cannot get there — so you never lose more of the picture than the limit actually requires. Every attempt is a real encode rather than an estimate, so the result is genuinely under the number, not near it. If the target cannot be reached at all it says so and tells you the closest it managed, instead of quietly handing back something larger. It works on JPEG, WebP and AVIF; PNG is lossless and has no quality setting, so for a PNG the tool offers to switch you to WebP, which can hit the target and still keep transparency.
Which format should I choose?
WebP is the best default — usually 25 to 35 percent smaller than JPEG at the same visible quality, and supported by every current browser. JPEG is the safest for sharing with old software. AVIF is smaller still but slower to encode and not available everywhere. PNG is lossless, so quality has no effect on it and the only way to shrink a PNG is to resize it or convert it to WebP. Only formats your browser can actually encode are offered.
Does compressing remove EXIF and GPS data?
Yes. Re-encoding through a canvas keeps only the pixels, so camera model, timestamps and GPS coordinates are all dropped from the file you download. Rotation recorded in EXIF is applied to the picture first, so it stays the right way up.
Is blurring or pixelating text safe enough to hide it?
Use Block for anything genuinely sensitive. Pixelation and blur discard less information than they appear to, and short predictable text such as a card number or an email address can sometimes be reconstructed from a pixelated image. A solid block cannot be undone because the pixels underneath are gone.
Can I crop or rotate an image and adjust it later?
Yes. The crop, the rotation and every shape and note are stored as instructions rather than baked into the pixels, so you can reopen the crop and move its edges, rotate again, or move a note at any point before you download. Only the file you download is flattened.
Does it cost anything, or need an account?
No. It is free, has no account, no sign-up, no watermark and no limit on how many images you compress or how large they are.
