Compress a Photo for Exam Registration

Competitive exam portals are famously strict: a photo between 20KB and 50KB, a signature between 10KB and 20KB, and JPEG only. Set the target and the tool handles the rest.

Why this compressor actually reaches your limit

Exact target file size

Say “200KB” instead of guessing a quality percentage. A binary search finds the highest quality that still fits your limit.

Batch compression

Add up to 30 images, optimize them in one run, and download everything as a single ZIP archive.

100% private

Images are decoded and re-encoded on your own device with the Canvas API. Nothing is uploaded to any server.

Automatic resizing

When quality reduction alone cannot reach the target, pixel dimensions are reduced step by step until it fits.

Your images never leave your device

Compression runs in a Web Worker inside your browser using the HTML5 Canvas API. There is no upload step, no temporary storage and no server-side copy — which is exactly why passport photos, ID scans and exam documents are safe to process here. Read the privacy policy.

Frequently asked questions

How do I compress a signature to 20KB?

Switch the target to 20KB. Signatures are simple black-on-white images, so they compress far below the limit with no visible change.

The portal says minimum 20KB — my file is smaller. What now?

Raise the target to the top of the allowed range and disable resizing so the tool keeps more data, which pushes the file size up toward the minimum.
