Image Compressor
Reduce an image towards a target size in megabytes, with an optional cap on the longest edge, showing the real before and after byte counts.
Runs in your browser — nothing is uploadedFree trial: 1 run of Image Compressor every day. After that, 2 credits per run.
Bring a photograph under a size limit you choose
Set a target size in megabytes and the encoder works towards it, lowering quality in steps until it gets close. Optionally cap the longest edge as well, which is usually the fastest way to shed weight from a phone photograph. Everything runs in your browser on files up to 50 MB, so nothing is uploaded.
What Image Compressor gives you
Target size rather than a guess
Ask for 1 MB and the encoder aims at it, instead of leaving you to try quality settings by trial and error.
Optional edge limit
Cap the longest side in pixels. Reducing a 4,000 px photo to 1,600 px often does more than quality alone.
Keeps your format
JPEG stays JPEG, PNG stays PNG and WebP stays WebP, so nothing downstream breaks on an unexpected file type.
Offers the original when it cannot help
If the compressed result is not actually smaller, you are shown the original instead of a pointless download.
Runs on your device
Compression happens in a background worker in your browser, so a private photograph never leaves the machine.
How to use Image Compressor
Add an image
JPEG, PNG or WebP, up to 50 MB.
Set your target
Enter a size between 0.05 MB and 10 MB, and optionally a maximum longest edge.
Compress
The encoder steps the quality down until it reaches your target.
Compare and download
Check the before and after figures, then download if the trade is worth it.

Questions about Image Compressor
Will quality drop?
Compressing to a size target is lossy. Compare the preview before downloading; if the result is larger than the original, the original is offered instead.
Is metadata kept?
EXIF and other metadata are dropped during re-encoding.
How do I reduce an image to under 1 MB for an upload form?
Enter 1 as the target size and compress. The encoder lowers quality in steps until it lands near that figure, so you do not have to guess at a quality percentage and try again. Anything from 0.05 MB to 10 MB can be asked for.
Why is the result slightly above or below my target?
The encoder works towards the figure by adjusting quality in steps and stops when it is close enough. Hitting an exact byte count would mean many more passes for no practical gain, so the final file usually sits just either side of what you asked for.
What is the best way to shrink a photo without it looking bad?
Cap the longest edge before pushing the target size very low. Resizing a 4,000 px photograph to 1,600 px removes far more weight than heavy re-encoding, and the result looks better because detail is discarded evenly rather than as compression artefacts.
Does compressing remove the location data from my photo?
Yes. EXIF and other metadata are dropped during re-encoding, which strips GPS coordinates — often exactly what you want before sharing a picture. It also removes the camera settings and the date, so keep your original if those matter.
Is the compression lossless?
No. Detail is discarded permanently to reach your target, so always keep the original if it has any value. If you need the same picture at the same quality in a different format, use Image Converter instead.
Can it compress an animated GIF or WebP?
No. Only a single frame is handled, so animated images are not supported. Still JPEG, PNG and WebP files all work.
