Why Compress Images to 100KB
100KB is the most common image size limit across Indian government portals, exam registration forms, and university applications. From UPSC photo uploads to SSC registration, IBPS bank exams to state PSC forms — nearly every competitive exam in India requires a photo under 100KB. Whether it is exam and government form uploads or sharing files on messaging apps, keeping your images under 100KB ensures faster delivery and trouble-free uploads. Our browser-based compressor adjusts JPEG quality to 70% and optimizes encoding — all without uploading your image to any server.
Best Settings for Exam and government form uploads
For exam and government form uploads, JPEG at 70% quality gives the best balance of file size and visual clarity. At this quality level, photos look clear at normal viewing size. Fine details may show slight softening when zoomed in at 200%+, but for on-screen use and print-at-size, results are excellent. If the result is still above the target size, try resizing to smaller pixel dimensions first using our Image Resizer.
Complete Privacy — No Server Uploads
Every step of the compression happens in your browser using the Canvas API and modern image codecs — your image is decoded, quality-adjusted, and re-encoded entirely on your device. This makes it safe to compress personal photographs, identity documents, medical records, and confidential certificates. No data leaves your computer, there are no daily usage limits, and you can process as many images as needed.

Will the photo still look clear after compression?
Yes. At 70% JPEG quality, the difference is invisible to the naked eye for passport-style photos. The tool optimizes encoding without degrading the visible areas.
