FAQs
Will compression change how my signature looks?
The tool offers a preview so you can compare original vs compressed. Lossless modes make no visual changes; lossy modes may slightly alter stroke edges—choose the quality level that balances size and appearance.
Which format is best after compression: PNG or JPG?
Use PNG if you need transparency. For smaller attachments where transparency isn't required, JPG can yield smaller files. WebP can be even smaller but isn't universally supported in all document editors.
Can I compress multiple signatures at once?
Yes — batch compression with consistent settings is available, and results are packaged into a ZIP for download.
Is my data private?
Processed files are typically stored temporarily and deleted after processing. Include a link to your privacy policy here to reassure users.
What if my signature becomes blurry after compression?
Try a higher quality setting or use lossless compression. You can also enable the 'sharpen' option after compression to restore edge crispness.
