Help Center & Troubleshooting Support — PDFCompress Pro
Get immediate solutions to common document processing questions, upload/download troubleshooting, and technical browser limits.
Troubleshooting Common Issues
1. Upload or Download Failed
Ensure your document is an uncorrupted, standard PDF or image file within browser memory limits (under 100MB). Check that aggressive ad-blockers or browser extensions are not blocking local blob generation.
2. File Size Exceeded for Portal Submissions
If your university or government portal requires files strictly under 200KB, use our dedicated Compress PDF to 200KB tool, which specifically optimizes DPI down to 72–100 DPI for text forms.
3. Password Protected PDFs
For security, encrypted files with user or owner passwords must be decrypted with their original password before compression or merging.
Browser Compatibility
PDFCompress Pro is fully supported on modern versions of Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, Opera, and mobile browsers (iOS Safari & Android Chrome).
