Frequently Asked Questions
Clear and detailed answers to the most common questions about document compression and optimization.
No artificial quantity limits. Since compression is processed directly in your browser and not on external servers, you can optimize as many documents as needed with complete privacy and zero constraints.
No, there are no artificial limits imposed by servers. Unlike other platforms that restrict you to 15 MB or 25 MB to force you into monthly subscriptions, ReptarDocs processes everything locally in your device's memory (Client-Side) with WebAssembly. Your documents never travel over the internet or consume cloud bandwidth, so you can optimize files of 50 MB, 100 MB, or more completely freely. The only physical limit is the available RAM on your device.
They are 100% safe. Your documents are never transferred over the internet. Neither we nor third parties can access your invoices, personal photos, or contracts.
The "Purge RAM" button serves two key functions for performance and confidentiality:
- Instant performance: When you compress large photos or PDFs, the browser retains temporary buffers in your device's memory. By pressing this button, all those megabytes are immediately released so your computer or mobile phone continues to run smoothly.
- Absolute privacy (0 traces): If you use a shared, office, or cybercafe computer and processed confidential files (payrolls, contracts, or IDs), the purge destroys any residue in the session memory so no one can recover it.
Does it affect your downloads? No, not at all. The files you already saved remain intact in your Downloads folder; only the browser's temporary working memory is emptied.
For 90% of cases, we suggest Recommended: it saves between 50% and 75% while maintaining great visual quality. If you need to send an urgent file via WhatsApp or upload it to a strict government portal, choose Extreme.
When processing more than one document, a top bar with the "Download All (.ZIP)" button will automatically appear to download all your optimized files in a single compressed file.
