When Chameleon-i refuses a CV or an upload hangs, the file is usually the problem — too large, the wrong format, or carrying characters the system doesn't expect. This guide helps you clear Chameleon-i upload errors quickly and keep your pipeline moving.
TL;DR: Chameleon-i upload problems come from oversized files (embedded images), unsupported formats (legacy .doc, scanned images), special characters in filenames, and browser session issues on big batches. Keep files small and text-based, use clean .docx or text-based PDFs, and upload in manageable batches. Distill automates the file prep.
Quick diagnosis: what's blocking the upload?
| Symptom | Likely cause | Quick check |
|---|---|---|
| Upload slow or times out | Large file with images | Is the file over ~2MB? |
| File rejected outright | Unsupported format | Is it an old .doc or a scanned image? |
| Error on a valid-looking CV | Special characters in the filename | Any symbols or accents in the filename? |
| Several uploads fail at once | Browser session or batch overload | Are you uploading a large batch in one go? |
Root causes ranked by frequency
Large files with images CVs carrying photos, logos, or design elements upload slowly and can time out in a browser-based system like Chameleon-i. Stripping images usually fixes it.
Unsupported or poor formats Legacy .doc files and scanned images are rejected or parse so badly they fail. Use .docx or a text-based PDF.
Special characters in filenames Symbols, emoji, or heavy diacritics in the filename can trigger upload errors. Use a plain filename like "Firstname Lastname - Role.docx".
Oversized batches in one session Uploading a large batch in a single browser session can stall. Smaller batches are more reliable, and a session refresh clears most hangs.
Step-by-step fix
- Strip images and compress. Remove photos and logos; keep files under ~2MB.
- Convert to a clean format. Save as .docx, or a text-based PDF if required.
- Rename the file. Plain alphanumeric filename, no symbols.
- Split the batch. Upload in smaller groups rather than all at once.
- Refresh the session if uploads hang mid-batch, then retry the failed files.
- Re-test with one clean file to confirm the fix before re-running the batch.
How to prevent Chameleon-i upload issues
- Standardise on .docx output for every CV that enters your workflow.
- Strip images at intake — client-ready branding can be re-applied on the way out.
- Keep a naming convention the whole team follows.
- Batch-prep files with Distill so every upload is clean, small, and consistently named.
When to automate this
- You upload 20+ CVs weekly into Chameleon-i.
- Upload failures interrupt sourcing sessions more than once a week.
- You also need CVs reformatted or anonymised before client submission.
Distill outputs small, clean, consistently named .docx files that upload to Chameleon-i without a fight.
