Compress image to a target size
Pick your images, type the size you need (for example 100KB), and the tool searches for the highest quality setting that still fits that limit.
Upload and process
Runs locallyHow to use it
- Drag your images into the box above, or click it to browse. Multiple files at once are fine.
- Enter the target size — for example 100 — and choose KB or MB.
- If the form also limits dimensions, set a maximum long edge in pixels (0 keeps the original size).
- Choose the output format: JPG is the most compatible, WebP is smaller at the same quality.
- Click compress. Download files one by one or grab everything as a single ZIP.
When this tool helps
Upload forms love strict limits — 100KB per image, 500KB per photo, 2MB per attachment. Guessing a quality slider until the file finally fits is tedious and often unnecessary. Here the target size is the input, not the outcome, so you get a file that passes on the first try. Because the compression runs entirely on your device, sensitive material like ID scans or contracts never leaves your computer.
FAQ
Are my images uploaded to a server?
No. The tool uses your browser's built-in image encoder, so files never leave your device. Nothing is stored, logged or shared.
Why is the result a little smaller than my target?
The compressor walks through quality steps and stops at the first one that fits your limit. Landing slightly under the target is expected behaviour.
Can PNG be compressed to 100KB?
Sometimes, but PNG is lossless so photographic images barely shrink. When the size limit matters more than the format, choose JPG or WebP.
Does compression reduce quality?
Yes — the trade-off is quality for size. This tool aims for the smallest loss that still meets your limit, which is far more predictable than guessing a quality percentage by hand.
Is there a file size limit?
Keep files under 30MB each and batches under roughly 40 images, since mobile browsers have limited memory.
