Self-Diagnostics & Quick Fixes

Troubleshooting & Diagnostic Guide

Encountering an unexpected error or slow processing when working with a file? Most issues are related to browser memory or local device constraints and can be solved quickly.

1. Large Files & Device Memory (RAM) Limitations

Because supported tools execute locally inside your web browser, processing very large files (such as 200MB+ PDFs or dozens of 50MP images at once) depends on your available system RAM.

Recommended Steps:

Process files in smaller batches (e.g. 5–10 images or split large PDFs into parts).

Close unnecessary browser tabs to free up system memory.

2. Corrupted, Incomplete, or Password-Protected PDFs

If a PDF file was damaged during download, has syntax errors, or is encrypted with a password, the browser rendering engine may not be able to parse the document structure.

Recommended Steps:

If the PDF requires a password, unlock it before merging or converting.

Try re-exporting or re-saving the PDF from your document viewer to repair broken internal references.

3. Camera Permissions & QR Code Scanner

When using the live QR Code Scanner, your browser must be granted camera access. If camera access was previously blocked or another app is currently using the camera, scanning will fail.

Recommended Steps:

Click the lock icon in your browser address bar and ensure Camera is set to "Allow".

Alternatively, take a picture of the QR code and use the "Upload Image" tab to decode it instantly.

4. Cached Script Issues & Hard Refresh

When new features or bug fixes are deployed, older cached JavaScript files in your browser can occasionally cause temporary mismatch errors.

Recommended Steps:

Perform a hard refresh: Ctrl + F5 on Windows/Linux or ⌘ + Shift + R on Mac.

Ensure your browser is updated to a modern version of Chrome, Firefox, Safari, or Edge.

Test in an incognito or private browsing window if extensions are causing conflicts.
