About this tool
At 100KB an image can stay genuinely sharp — sharp enough for a scanned result card, a readable document page or a good-quality profile photograph — while still being tiny compared with the 3MB or 4MB file your phone produces. Many government portals, embassies and university systems set their limit exactly here. This compressor targets 100KB automatically: it eases the JPEG quality down first, preserving full dimensions wherever possible, and only scales the picture if the limit cannot be met otherwise. Everything runs locally in your browser, which is the safest way to handle scans of certificates, ID documents and personal photographs.
How to use it
- Pick the photo or scan you want to reduce — JPG, PNG and WebP are all accepted.
- Leave the target on 100KB, or choose another value between 10KB and 200KB to match your portal exactly.
- Click 'Compress image' and let the tool find the highest quality that still fits under the limit.
- Preview the output, confirm the displayed size is under 100KB, and download it.
Where it is used
- Online admission systems that allow photographs up to 100KB.
- Scanned documents — result cards, domicile and certificates — that must stay readable after compression.
- Embassy and visa document uploads with a 100KB per-file limit.
- Sending clear photos over slow connections or limited mobile data in Pakistan and India.
Tips for a better result
For documents, photograph or scan the page flat, in good light, with the page filling the frame; a straight, even image compresses far better than a tilted one. If your 100KB file must also be a particular size — many portals ask for 350 by 450 pixels, for example — use the Image Resizer first and compress afterwards. Keep your original file safe: compression to 100KB is a one-way step, so archive the full-size version separately.
