[email protected]Drifter on the web accepts PDFs; images (PNG, JPG, GIF, WEBP, BMP, HEIC/HEIF, SVG, TIFF — multi-page TIFFs keep every page); Word documents (DOCX); rich text (RTF, converted to readable text); spreadsheets (XLSX, XLS, XLSM, CSV); saved emails (EML and Outlook MSG — attachment names are listed, attachments themselves are not converted); Markdown; source code and data files (JSON, XML, YAML, and more); and plain text (TXT, LOG)
The Drifter app for iPhone and iPad accepts PDFs; images (PNG, JPG, GIF, WEBP, BMP, HEIC/HEIF, TIFF); Word documents (DOCX); spreadsheets (XLSX, XLS, XLSM, CSV); RTF; plain text (TXT, LOG); rendered Markdown (MD); and the same source code and data files.
New formats get added regularly — let me know what you'd like to see supported.
No. All conversion happens in your browser (web version) or on your device (native app). Files never leave your device. See the Privacy Policy for the full details.
For most file types, conversion is near-instant. Two exceptions are worth knowing about:
If the progress indicator stops moving for more than a minute, refresh the page and try with fewer files.
The most common causes:
Hover the status chip on the failed item in the queue for the specific error message.
Yes, on desktop. Drag any file in the queue by its handle (the dotted icon on the left) to reorder. The final PDF preserves the order shown.
On iPhone and iPad, drag reorder isn't available in Safari — touch devices don't fire the underlying drag events the browser needs. The simplest workaround is to remove the misordered file with the ✕ button and re-add it in the position you want. The Drifter app for iPhone and iPad supports full drag-to-reorder.
Yes. Click the rotation chip next to any file to switch between auto, portrait, and landscape. The choice persists until you remove the file. Click the eye icon to preview each file at its current orientation before merging.
For PDFs, yes — they're embedded byte-for-byte with no re-rendering. For images, yes — pixels are preserved. For Word documents and spreadsheets, the web version renders the layout into the PDF and it may differ slightly from how Word or Excel would print it natively (fonts substitute to system fonts, and complex formulas show their computed values). The Drifter app for iPhone and iPad converts Word and Excel on-device as well, using Apple's own text engine for the layout.
Yes, after your first visit. The web app installs as a Progressive Web App on iOS and Android home screens, and once installed it works without an internet connection. On the desktop, you can also use it offline by re-loading the same browser tab.
Open the web app in Safari, tap the share button at the bottom of the screen, scroll down, and tap "Add to Home Screen." It will appear with the Drifter icon and run full-screen like a native app.
Drifter: PDF Toolkit for iPhone and iPad is coming to the App Store very soon. It combines PDFs, images, camera scans, Word, and Excel into a single PDF — with drag-to-reorder, page rotation, full-screen preview, and Share Sheet integration, all on your device. Drifter Pro launches with it: Make Searchable (OCR), Watermark, Set Password, and Reduce Size, unlocked with a single one-time purchase. Email [email protected] to hear about new releases.
The web version is free, forever. The Drifter app for iPhone and iPad is free to download, and the core combine features are free and unlimited — no watermarks, no page limits. Drifter Pro is a single one-time In-App Purchase through the App Store — never a subscription — and every future Pro feature is included once you own it. Family Sharing is supported.
Email [email protected] with the format or workflow you'd like to see. Every feature request actually gets read — most updates start that way.
