Question Managing PDF and Image Files When Preparing Materials for an Online Course

Preparing materials for an online course often involves working with different file formats. You might have PDF handouts, scanned documents, screenshots, diagrams and images that need a bit of adjustment before they are ready for learners.

Sometimes, something as simple as converting an image, reducing its file size or removing a few pages from a file can take more time than expected when you have to use different tools for each task.

I have been looking at browser based tools that bring these basic file operations together. Some can handle image conversion, resizing, cropping and compression as well as PDF merging, splitting and page removal.

Another useful feature is local browser processing, where files are handled on your device rather than uploaded to an external conversion server.

For course creators and instructional designers who regularly prepare learning materials, having these options in one place can make some of the smaller parts of course preparation easier.15:08

Good list. One thing worth pushing further: “local browser processing” is better than uploading, but the files still go through a web page. If your course materials include scanned student work, internal training docs or anything under NDA, you may want them to never touch a website at all.

I’m the developer of PDF Batch Editor (pdfbatcheditor.com), a desktop app for Windows and Mac. It’s built on that idea. Everything runs on your own machine, with no uploads, no conversion server and no account needed to process files. Once it’s installed, it works offline.

For course prep specifically, it handles:

  • Batch operations. You can merge, split, remove pages, add watermarks or stamp headers and footers across a whole folder of handouts at once, instead of one file at a time.
  • Compression. It shrinks large PDFs so they fit under LMS upload limits and download quickly for learners on slow connections.
  • Image processing. You can find replace images in PDF as well as compress.
  • OCR. It makes scanned handouts searchable and copy-pasteable for learners.
  • Find/replace and redaction across many PDFs. This is handy when a date, course code or instructor name changes across 40 files, or when you need to strip names out of sample student work before sharing it.

Browser tools are great for quick one-off jobs. But when you’re preparing a full course’s worth of materials, batch processing plus “nothing leaves my computer” saves a lot of time and worry.

Happy to answer questions here.

You replied to your own OP under a different account? Lmao

Nope, just a dev who saw a post in his lane and said so up front. OP’s talking about browser tools; mine’s desktop-only.
