Frequently asked questions
Are my files uploaded anywhere?
No. Every SnapToolz tool runs entirely in your browser using JavaScript and WebAssembly. Files are read locally, processed in memory, and the result is offered as a download. There is no backend.
Which PDF tasks does SnapToolz cover?
Most everyday PDF workflows: merging, splitting, compressing, rotating, page-organising, page extraction, page numbers, watermarking, cropping, repairing, unlocking, metadata editing, signing, plus PDF↔image, PDF↔Word and PDF↔Excel conversion.
Can I work with confidential PDFs?
Yes — that's exactly the use case SnapToolz is best at. Because every operation runs in your browser, NDAs, contracts, medical records and tax documents never leave your device.
How is this different from iLovePDF, Smallpdf and other online PDF tools?
Those tools upload your file, process it on their servers, and stream the result back to your browser. That round trip is what makes them slow on mobile, and what makes them privacy-unfriendly for sensitive documents. SnapToolz does the work directly in your browser via WebAssembly — no upload, no daily quota, no email signup, no watermark on the output. The trade-off: very large files (>200 MB) are constrained by your device's RAM rather than a server's.
Is there a file-size limit?
No artificial limit. Practical limits depend on your device's RAM. Modern laptops handle 200+ MB PDFs comfortably; older phones may struggle past ~50 MB on memory-hungry operations like compression.
Do you add a watermark to the output?
No. Outputs are clean — we never watermark, never alter, never inject anything into your PDFs. The whole site is free with no paid tier, no upsell, and no daily limit.
Is everything free?
Yes — every tool in this category and on the entire site is free with no sign-up, no daily limit, and no watermark.
