Core tool
Compress an image to 100 KB
Just under 100 KB, every time.
Drop a photo and get it back just under 100 KB — the size asked for by job applications, university portals and visa forms.
Each file lands just under this size.
If quality alone can't reach the size, the image is scaled down until it fits. The new size is shown on the file.

How to use it
- 01Drop your image, or paste one with Ctrl+V. JPG, PNG, WebP and HEIC all work.
- 02The target is already set to 100 KB — change it if your form asks for something else.
- 03Tap Compress. Quality is lowered step by step, and the photo is scaled down only if that's the only way to reach 100 KB.
- 04Compare the result with the original, then download.

Questions, answered
How do I make a photo exactly 100 KB?
Drop it above and tap Compress. The target is already 100 KB, and each file comes back just under that — the quality that was needed is shown on the file, so you can see how hard it had to work.
Will my photo still look good at 100 KB?
It depends on the dimensions. A passport-sized photo at 100 KB looks fine; a full-size camera photo squeezed to 100 KB will soften. Use Compare before downloading, and crop or resize first if you only need part of the image.
What if the form also wants exact dimensions?
Resize first, then compress. The resize tool has presets for passport photos (35 × 45 mm) and common pixel sizes, and compressing afterwards keeps those dimensions unless the size target can't be met any other way.
Why does the form ask for 100 KB?
Upload limits keep storage and bandwidth predictable — 100 KB is a common one for job applications, university portals and visa forms. The limit is about the file size in kilobytes, not how large the photo looks on screen.
Is my photo uploaded anywhere?
No. Compression runs in your browser, so the photo never leaves your device — which matters when you're sending ID documents to a form.
