Naming and Organizing Compressed Images for Signature Uploads

Updated May 20, 2026 · 7 min read

Good file names help you, your team and search engines. 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.

Naming and Organizing Compressed Images

Use short, descriptive, lowercase names with hyphens, such as blue-ceramic-mug-front.jpg. Our tool keeps your original name and adds a suffix so you can tell copies apart.

Store compressed images for signature uploads in their own folder so you never upload a full-size original by mistake.

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.

FAQ

What JPEG quality should I use for e-learning courses?

Quality around 78 keeps photos looking natural while cutting file size substantially.

Will compressing reduce image quality for e-learning courses?

Some detail is removed, but at sensible settings the difference is not visible at normal viewing size.

How do I compress many images for e-learning courses at once?

Drop all of them into the tool together and use Download all to get a single ZIP.

Wrapping up

For signature uploads, the reliable recipe is simple: resize to around 300 pixels, compress at quality 60 or to a 20 KB target, and check the result before you upload. Keep the original so you can always start again.
