Questions & Answers
Frequently Asked Questions
Yes. Enter 50 in the Target Size field and click Compress. Our tool uses a binary search algorithm to automatically adjust JPEG quality until the file size falls below your target. It tries up to 15 iterations to find the optimal quality setting.
Absolutely not. Everything runs in your browser using the HTML5 Canvas API. Your photo never leaves your phone or computer. Zero server interaction for the actual compression. Complete privacy — even your internet connection is not used during compression.
Upload your PNG image, select "JPG / JPEG" as the Output Format, set your target KB size, and click Compress. The tool converts and compresses in one step. Almost all government exam forms require JPG format.
For CUET: Photo should be 200×230 pixels (use the "Photo 200×230" preset button) and signature 140×60 pixels. For SSC: 100×120 px for photo. Always check the official exam notification as requirements can change per year.
If the target is extremely small for the given image, the tool compresses to the minimum possible quality (JPEG 1) and shows a warning with the achieved size. In this case, try reducing the dimensions first (e.g. 200×230) which dramatically reduces file size.
Yes. Upload your signature image, use the "Sign 140×60" dimension preset, set target to 10 or 20 KB, select JPG, and compress. This meets requirements for CUET and most other government exam signature uploads.
