Convert an image
Move between JPG, PNG and WebP, set the quality, bring the dimensions down.
How to use it
Drop the image in
Drag it into the area above or click to choose.
Format, quality, size
Three settings, and the result updates the moment you touch any of them. The “After” frame on the right shows you exactly what you are giving up.
Download when you like it
The saving line says how much smaller it got than the original. To move on to another image press “Replace” — the picker opens straight away.
Which format should I pick
Photos and sharing
The most widely supported format; it opens everywhere. The right choice if you are sending it to someone or uploading it into a system.
Screenshots and graphics
Logos, hard-edged graphics, transparent backgrounds. It is lossless — which is why the quality slider switches off when you pick PNG.
Websites
Clearly smaller than JPG at the same quality. Every modern browser opens it; for a website it is the best of the three.
What the quality setting does
Print and archive
Almost nothing is thrown away and the file stays large. Stay here for images that will be edited again later.
The default range
The right place for web and sharing. On most photographs 82 is indistinguishable by eye.
A hard size limit
For when the file has to get under a ceiling. Blotching starts to show in flat areas.
JPG and WebP are lossy formats: to make the file smaller they throw away detail your eye does not register. PNG is lossless.
Common questions
Can I enlarge the image?
Not in this tool, deliberately: stretching a small image adds no detail, it only blurs it. If you really want it bigger, Image Upscaler rebuilds the lost detail.
How much quality does compression cost?
You see the result directly in the “After” frame on the right. Compare the two side by side and move the setting until you are happy.
Do EXIF and location data survive in the output?
They do not. Re-encoding in the browser drops the EXIF block — a photo that passes through this tool carries no location or device information. If that is all you want, Remove EXIF Data is a more direct route, because there you see what was in the file first.
The HEIC file from my iPhone will not open
Most browsers cannot read HEIC. There is a separate tool for it: HEIC to JPG.
