Free Online Photo Resizer
Resize and compress any picture to an exact KB size or pixel dimension — for exam forms, uploads or sharing — right in your browser.
Upload your image to PhotoResizer, type the target size you need (e.g. 20 KB, 50 KB or 100 KB) or exact pixels, and download. It’s free, private and needs no sign-up.
Resize by KB or by pixels
Some uploads cap the file size (“max 50 KB”); others fix the dimensions (“200×230 px”). PhotoResizer does both — enter a KB target and it compresses to fit, or enter width and height in pixels or cm and it scales exactly, keeping the picture as sharp as possible.
Why compress in the browser
Uploading a private photo to a random online compressor is a privacy risk. PhotoResizer processes everything on your own device — nothing is sent to a server — so it’s safe for ID photos, signatures and documents. It also adds no watermark, unlike many “free” tools.
Need an exam-specific size instead? Use the photo & signature resizer for exams for ready presets, or the signature resizer for a 10–20 KB signature.
How to resize a photo to an exact size
- Upload your image — JPG, PNG or WebP from your phone or computer.
- Enter the target — a KB size (20/50/100 KB) or exact width × height in pixels or cm.
- Preview — check the resized image stays clear at the smaller size.
- Download — save the compressed image instantly. No sign-up, no watermark.
