Four ways to get content onto your reMarkable

However you work, there’s an entry point that fits. Uploads run in the background and finish even after you close the app.

Drag & Drop

Drop PDFs, images, and text files directly onto the app window. The upload starts immediately.

Share Sheet

Share from Safari, Mail, Finder, or any Mac app using the system share menu. No app switching needed.

Print to reMarkable

From any app’s Print dialog, choose “Print to Klass-RM Uploader” from the PDF menu. Works in Word, Pages, Safari, and Preview, or anywhere you can print.

Folder Watching

Point the app at a folder. Any PDF or image you drop in is automatically uploaded, no clicks required.

Pro feature

Works with every app on your Mac

If it can share, print, or save to a folder, Klass-RM Uploader can send it to your reMarkable.

Safari

Mail

Word & Pages

Finder

Preview

Any app that prints

Any content, delivered clean

PDFs, images, web articles, text, comics, and sticker packs. Every format arrives ready to read and annotate.

PDFs

Drop any PDF and it appears on your reMarkable in seconds. Annotations, forms, research papers, documents. Everything is preserved.

Web Articles

Paste any article URL. The app fetches the page, strips navigation and ads using the same algorithm as Firefox Reader Mode, and delivers a clean EPUB with embedded images to your reMarkable.

Converted to EPUB, readable and scrollable on device

Images

JPEG, PNG, GIF, HEIC, HEIF, TIFF, BMP, and WebP are all supported. Send diagrams, photos, or sketches with no conversion step.

Text & Markdown

Drop a plain-text or Markdown file and it arrives as a clean EPUB. Markdown formatting - headings, lists, emphasis, links, and code - is rendered, and images referenced in the file are embedded.

Converted to EPUB, readable on device

Comics (CBZ & CBR)

Drop a CBZ or CBR comic archive and it is converted to a downsampled PDF that reMarkable can read, automatically kept under the upload size limit. Page images are re-encoded so even big collections sync cleanly.

Pro feature

Sticker Packs

Build a sticker pack from your own images, or buy a sticker pack from somewhere, and send it as an editable reMarkable notebook where every sticker is its own copyable object you can paste anywhere. Pick a target device, display size, and quality. Transparency is preserved.

Free up to 5 stickers; Pro for unlimited. Requires Connect.

Pro feature

Free for everyone

Send straight from the macOS share menu

Klass-RM Uploader installs into the macOS share sheet, so it is one click away in Finder, Safari, Mail, Preview, and any app that can share. Send a file or a web page to your reMarkable without exporting first or switching apps.

Built into the share menu Hit Share in Finder, Safari, Mail, Preview, or any Mac app and choose Klass-RM Uploader. Send PDFs, images, text, Markdown, comics, sticker packs, or a web URL.
PDF or Notebook, right from the share sheet Pick how it arrives without opening the app. Notebook delivery needs a Pro license and reMarkable Connect.
Large files optionally get optimized Big PDFs are downsampled to sync fast and stay under the upload limit, the same as a drag and drop.
No app switching The upload starts in the background and finishes on its own, so you stay in whatever you were doing.

Pro feature

Send as reMarkable Notebook - annotate immediately

With a Pro license and a reMarkable Connect subscription, every upload can appear as an editable Notebook instead of a static file. Start writing the moment it arrives.

Editable on device Arrives as a native reMarkable Notebook. Add handwriting layers, annotations, and highlights right away - no conversion step needed.
Works from every entry point Drag and drop, share sheet, print helper, and folder watching all support Notebook mode when your Pro license is active.
Requires reMarkable Connect Notebook conversion is a reMarkable cloud feature. A Pro license enables it in the app; Connect enables it on the reMarkable side. Both are required.

Pro feature

Drop a folder. Walk away. Files appear on your reMarkable.

Watch one or more folders at once. Klass-RM Uploader monitors them continuously and uploads new files the moment they arrive.

File stability wait A configurable 1 to 600 second delay before uploading, so partially-downloaded or in-progress files are never sent incomplete.
Post-upload disposition Leave the file in place, move it to an “Uploaded/” subfolder, or delete it automatically after a successful upload.
Deduplication SHA-256 fingerprinting means the same file content is never uploaded twice, even if it’s renamed or copied.
Per-folder format Choose PDF or Notebook format independently for each watched folder. Notebook requires Connect.

Free for everyone

Big PDFs, optimized to sync fast

Large PDFs can be slow to sync and eat storage on your reMarkable. Klass-RM Uploader can shrink them automatically before they go up - no license required.

Configurable size threshold Files over your chosen size (default 100 MB, adjustable 25 to 500 MB) are rebuilt at a quality preset you pick. Smaller files upload untouched.
Downsample and flatten Pages are rasterized and downsampled, which also flattens layers and annotations into a clean, lightweight document.
Automatic splitting If downsampling alone is not enough, the document is split into numbered parts that each stay under the limit.
Comic archives, too CBZ and CBR comics are converted to a downsampled PDF and kept under the upload size limit, so even large collections sync cleanly. Comic conversion is a Pro feature.
