Compress images online
Make JPG, PNG and WebP photos smaller in a few seconds. Choose a quality level, optionally shrink the width, and see the size before and after for every file. Everything happens in your browser, so your photos are never uploaded.
Everything runs on your device. Nothing you add or type is sent to any server.
How to use it
- 01
Drop one or more images into the box above, or tap it to pick photos from your phone or computer.
- 02
Move the quality slider. Lower quality gives a smaller file. If you need it even smaller, enter a maximum width in pixels, or choose JPG or WebP as the output format.
- 03
Press Compress. Check the new size next to each file, then download them one by one or all together as a ZIP file.
When a smaller image helps
Many online forms for jobs, exams, scholarships and government services ask for a photo or signature under a certain size in KB. Email services limit attachment size too, and light images make websites faster. Phone cameras save large, detailed photos, so the original file is often much bigger than these uses need.
Always read the exact limit on the form you are filling. If it also asks for exact pixel dimensions, use the Resize Image tool first, then compress the result here.
How the quality setting works
JPG and WebP are lossy formats: they keep the image looking similar while dropping detail your eye barely notices. The slider controls how much detail is kept. Start around 75, look at the preview, and go lower only if the file is still too big.
PNG is lossless, so the quality slider does not change a PNG that stays PNG. To shrink a PNG photo a lot, choose JPG or WebP as the output, or reduce its width. JPG has no transparency, so transparent parts of a PNG become white.
If the compressed file comes out bigger than your original, the tool keeps the original and tells you, unless you asked for a new format or width.
Private by design
Your photos are processed by your own browser and never sent to a server. A newly saved file also leaves out hidden camera details such as the camera model and location. An original that is kept unchanged still has them.
Frequently asked questions
How small can I make my image?
It depends on the photo. Lower the quality and width step by step until the file fits your limit, checking that the preview is still clear.
Will compressing reduce the photo's dimensions?
Only if you enter a maximum width, or a side is over 16,384 pixels (this tool's limit). Otherwise the width and height stay the same and only the file size changes.
Is there a limit on files?
Each image can be up to 50 MB. You can add many images at once; very large batches depend on your device's memory.
Why did one file not get smaller?
Some images are already well compressed. When re-saving does not help, the original is kept. Try a lower quality, a smaller width, or WebP output.
