About PDF tools & the PDF format
Why browser-based PDF utilities matter for privacy and everyday work.
Portable Document Format (PDF) is the standard way to share documents that should look the same on any device — contracts, invoices, ebooks, scanned forms, and slide decks. Unlike Word or Pages files, a PDF locks in fonts and layout so recipients see what you intended. That same strength makes PDFs harder to edit without dedicated software, which is why people merge reports, split chapters, compress archives for email, or extract pages as images for presentations.
Traditional online PDF converters often upload your file to a remote server. That creates privacy risk for financial statements, medical records, or client work. DoItSwift PDF tools run with JavaScript inside your browser: PDFs are read from your disk into memory, processed with libraries such as PDF-lib and Mozilla’s PDF.js, and downloaded back to you — no account, no cloud queue, no retention on our side.
Use cases include combining invoices into one packet, pulling a single signed page from a scan, shrinking a camera PDF before WhatsApp, turning slides into JPGs for social posts, and building a photo album PDF from vacation JPGs. Because everything is local, you can disconnect from the internet after the page loads and keep working. Very large files (hundreds of pages or 50MB+) may take longer or stress older phones; close other tabs for best performance.
PDF tools FAQ
Is there a file size limit?
We do not impose a fixed cap — limits come from your device RAM and browser. PDFs above ~50MB may take a noticeable time to process; very large files can fail on low-memory mobile browsers.
Are my PDFs uploaded to DoItSwift?
No. Tools load PDF-lib and related code from CDNs, but your document bytes stay in the browser unless you choose to download the result. You can verify by going offline after the page loads.
Can I process multiple PDFs in one session?
Yes — merge, compress, and PDF-to-JPG support batches. Split focuses on one document at a time for clarity. JPG-to-PDF accepts many images at once with reordering before export.
Will compression always make files smaller?
Usually, but not always. “Light” modes mostly re-save and strip metadata. Heavier modes may rasterize pages, which trades smaller size against sharp text — pick the level that fits your document type.
Do these tools add watermarks?
No. Output is whatever the conversion produces — no DoItSwift branding on your files.
Which browsers work best?
Latest Chrome, Edge, Firefox, or Safari on desktop. Mobile Safari and Chrome work for moderate file sizes.
