Compress image to 100KB
Need a photo under 100 KB for a form, an email or a website? This tool automatically adjusts quality and dimensions until your image fits the limit — everything stays on your device.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop your image into the box — the 100 KB target is preset.
- The tool searches for the best quality that keeps the file under 100 KB.
- Download the compressed image and verify the final size next to the file.
Good to know
100 KB is the most common limit on the web, and it is a comfortable one: a photograph around 1000 × 1300 pixels fits with quality to spare, which is more than enough for an application form, a profile picture or an email attachment.
Content matters as much as size. Images with fine detail — foliage, textured fabric, crowds, text — compress worse and may need fewer pixels to fit. Images with large flat areas, like a face against a plain background or a scanned document, compress far better and can keep more resolution.
You can drop a whole batch here: each file is compressed to the target independently, with no limit on how many. If several photos need the same treatment for the same form, do them in one go.
Frequently asked questions
How much quality do I lose at 100 KB?
For typical photos up to about 1920px wide, 100 KB keeps very good visual quality. Larger images are scaled down as needed; the tool always tries quality reduction first.
Can I compress several images to 100 KB at once?
Yes. Drop as many files as you want — each one is compressed to the target independently, with no batch limits.
Does this work with PNG and WebP too?
Yes. JPG usually reaches 100 KB with the least visible change; PNGs with photographic content may need resizing or conversion to JPG for best results.
Is it really free and private?
Yes. There is no account, no watermark and no upload: the compression code runs in your browser and your files never leave your device.
Is 100 KB enough for a photo that will be printed?
For a small print — a passport photo or a 10 × 15 cm snapshot — yes. For anything larger, print needs far more detail than 100 KB can carry, and you should send the original instead. This limit exists for screens and forms, not for printing.
Can I compress a scanned document to 100 KB?
Usually with room to spare. Scans are mostly flat white with sharp text, which compresses very efficiently, so a single page often fits well under the limit while staying perfectly legible.
