— Browser-only processing

Your PDFs never leave your device — perfect for contracts, resumes, and other sensitive documents.

Tools like SmallPDF, iLovePDF, and Adobe's online suite upload your file to the cloud. This site does the opposite — every operation runs in your browser's memory. Five tools (Merge PDF, Split PDF, PDF Edit, Image to PDF, PDF to Image) are free, with no signup. There are no watermarks, logos, or ads added to your output. All libraries are vendored (committed locally) so there is no external CDN dependency.

Frequently asked questions

Do my uploaded PDFs really stay local?
Yes. All processing happens in your browser via JavaScript and WebAssembly. Merge, split, edit, and image-to-PDF use pdf-lib (MIT); PDF-to-image and edit thumbnails use pdf.js (Mozilla, Apache-2.0), all client-side. Even the site operator cannot see your file contents — nothing is uploaded.
Can I work with password-protected PDFs?
Password-locked PDFs may not process automatically. This site does not provide decryption. Unlock the PDF in a viewer first, then upload. The ignoreEncryption flag bypasses some light protections, but strong passwords will not work.
How large can my PDFs be?
On desktop Chrome, around 200MB and 200 pages is comfortable. Mobile is best kept under 50MB and 50 pages. If memory is tight, narrow the range with Split PDF first. The edit tool is more conservative because of thumbnail rendering.
Are fonts, images, and hyperlinks preserved?
pdf-lib copies page objects from the original, so fonts, images, and most hyperlinks are preserved. Interactive form behavior, digital signatures, and certain annotations may behave differently after editing.
It's flaky on mobile
Mobile Safari and Chrome have memory limits around 500MB, so large PDFs are best handled on desktop. In-app browsers (e.g. messaging app webviews) are unsuitable for video/PDF work — use the 'Open in external browser' option (an auto-banner is shown).
