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
- Choose an image or PDF.
- Review the instant size and type check.
- 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.
