How to compress an image to 100 KB
Drop the image and it is compressed to the highest quality that fits under 100 KB, automatically. The page tries several quality levels and keeps the best one that meets the limit, so you do not have to guess. Batch drop is fine: each file gets its own best quality. Check the before/after view and download.
If it cannot reach 100 KB
Large photos straight from a phone are 3–5 MB at 4000 px wide. Lower the maximum width to 1600 or 1920 px, which is still full-screen size, and most will fit under 100 KB at a good quality.
Where this limit comes up
Government and exam forms, job portals, university applications and visa uploads often cap photos and documents at 20, 50 or 100 KB. The limit is on the file, so a large but efficiently compressed image passes.
Nothing is uploaded
Compression happens on your device in the browser. The photo is never sent to a server, so it is fast, private and has no file limit.
