How to compress an image to 25 KB
- Drag your JPG, PNG or WebP into the box above — it's read straight into your browser, never uploaded.
- The target is already set to 25 KB; FileTinker re-encodes the image until it fits at or under that size.
- Preview the result and download. If 25 KB is too small for this image, you're told clearly instead of handed a broken file.
About compressing to 25 KB
Compressing to 25 KB reduces a photo's file size by re-encoding it more efficiently and, when needed, lowering quality slightly — handy for upload limits, email attachments and forms that cap files at 25 KB.
Everything runs in your browser, so your image never leaves your device. JPG and WebP reach small targets like this most easily; very small targets may trade away some visible quality.
Frequently asked questions
How do I compress an image to 25 KB?
Drag your JPG, PNG or WebP into the tool above, leave the target at 25 KB, and press Compress. FileTinker shrinks it to 25 KB or under in your browser, then you download the result.
Will compressing to 25 KB reduce the quality?
Smaller targets mean more compression, so some quality is traded for size. FileTinker keeps the highest quality that still fits under 25 KB; if 25 KB is very small for a detailed photo, the tool tells you the closest size it could reach.
Are my images uploaded anywhere?
No. Compression happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
Which formats can I compress to 25 KB?
JPG, PNG and WebP. The compressed file keeps its original format.
