Use our dedicated tools for precise compression to your specific target: compress photo to 5 KB, compress photo to 10 KB, compress photo to 15 KB, compress photo to 20 KB, or compress photo to 30 KB.

Why Exam Signatures Must Be Compressed

Government exam portals impose strict file size limits on signature uploads to ensure fast and reliable form submission. A signature file between 4 KB and 20 KB uploads instantly and eliminates the risk of timeout errors during the application process.

Smartphone photos of signatures can easily be 500 KB to 2 MB — far larger than the 20 KB limit set by most exam portals. Our signature resizer compresses these files down to the required size while maintaining legibility. The tool uses intelligent JPEG compression to reduce file size without blurring the signature strokes.

A well-compressed signature image retains all the identifying characteristics needed for verification while being small enough to upload quickly. Our tool automatically finds the optimal compression level to meet your target file size while keeping the signature sharp and clear.
