Should You Strip EXIF Data From Images for Signature Uploads?

Updated June 9, 2026 · 7 min read

Photos carry hidden metadata such as camera model, date and sometimes GPS location. Signature images are simple black-on-white marks, so they can be very small while staying perfectly legible.

Recommended settings for signature uploads

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 300 px on the long edge
Quality60
File size20 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Should You Strip EXIF Data From Images

For anything shared publicly, removing that data protects your privacy and shaves a few kilobytes. For signature uploads, there is rarely a reason to keep it.

When our tool re-encodes an image through the browser canvas, metadata is not carried over, so the downloaded file is clean by default.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 20 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 300 and the target size to 20 KB.
  4. Press Compress, check the result and download it.

  • Write a size limit slightly below the stated maximum to leave a margin.

Wrapping up
