Shrink JPG, PNG and WebP photos by quality or to an exact size like 20 KB, 50 KB or 100 KB for government form uploads.
About Image Compressor
This image compressor online shrinks JPG, PNG and WebP photos for exam forms, job portals and email. Use Target size mode and type the limit the form asks for, such as 20 KB, 50 KB, 100 KB or 200 KB, and the tool finds the best quality that fits. Or use Quality mode to reduce photo size by eye.
A before-and-after slider lets you check that the photo still looks clear. You can compress many images at once and download them together as a ZIP. Photos are processed in your browser and never uploaded, which matters for ID photos and signatures. It is free, with no sign-up and no watermark.
How to use Image Compressor
- Drop one or more photos (or try the sample).
- Choose Quality mode, or Target size and enter the KB limit your form asks for.
- Compare before and after with the slider.
- Download each file or all of them as a ZIP.
Frequently asked questions
How does target size mode work?
It repeatedly re-encodes the photo, searching for the highest quality that stays under your limit. If even the lowest quality is too large, the photo is scaled down step by step until it fits.
Are my photos uploaded?
No. Compression uses your browser’s canvas encoder, so files never leave your device.
Why is my PNG output a JPG?
PNG is lossless and cannot be compressed by quality. Choose JPG or WebP for small files. Transparent areas become white in JPG.
Which is smaller, JPG or WebP?
WebP is usually 25–35% smaller at the same visual quality, but some older portals only accept JPG.
How do I compress an image to 50 KB?
Choose Target size, enter 50 KB and drop your photo. The tool lowers quality step by step until the file fits, then you can download it.
How can I reduce photo size without losing quality?
Start with Quality mode around 80%, which usually cuts size a lot with no visible change. Compare with the slider, and only go lower if the file is still too big.
