Quickly compress your digital signature to a smaller file size (KB or MB) without sacrificing quality. Our Online Signature Compressor ensures your signature meets strict file size requirements for government forms, applications, and documents, making uploads instant and error-free.
Digital signature files often start out large, especially if they are high-resolution scans or captured in lossless formats like PNG. When uploading these signatures to official portals, you frequently encounter errors because the file exceeds the maximum allowed size (e.g., 50KB or 100KB).
Our compressor uses advanced lossy and lossless algorithms to optimize your signature. For JPEG files, we reduce data redundancy and apply selective compression based on the quality level you choose. For PNG files, we optimize color palettes and use smart filtering to shrink the file size dramatically while maintaining transparency and clarity.
This tool is essential for:
Lossless compression keeps your signature identical. Lossy compression reduces file size further but may slightly affect edge sharpness, depending on the level you choose.
Download PNG if you need transparency. If not, JPG usually results in smaller file sizes and is ideal for email or online forms.
Yes, the tool supports batch compression and downloads your optimized signatures in a ZIP file.
Most tools delete processed files automatically after completion. Include your site’s privacy policy link to reassure users.
A signature between 250–350 px wide and under 40 KB works best for fast email delivery.
