Private preparation on your device

Prepare supplier images and PDF files for upload

Check file size and type before registration. Image compression stays on your device; a valid prepared file is then uploaded temporarily for registration and removed if unused.

How to use this tool

  1. Choose an image or PDF.
  2. Review the instant size and type check.
  3. For an image, download a smaller WebP copy; for a PDF, follow the preparation guidance.

PDF preparation guidance

  • Keep only relevant product pages and remove blank pages.
  • Re-export scans at about 150 DPI in grayscale when colour is unnecessary.
  • The final PDF must be 256 KB or smaller and must not contain scripts, embedded files or auto-open actions.

This browser tool checks PDFs against the safe upload limit. It does not rewrite PDFs because that can damage signatures or document structure.
