Edit PDFs Free in Your Browser: No Upload Needed
Merging, splitting, rotating, compressing and reading PDFs can run entirely on your machine; here is how that works and where the honest limits are.
PDF Guides
Editing, merging, compressing and extracting from PDF files without uploading them anywhere. Includes the metadata story most senders never check, and the honest limits of what browser tools can do with the format.
Turn Images, Text or Markdown into a PDF
Photos into a tidy document, text that opens everywhere, Markdown with formatting for free: the creation tools and the layout decisions behind them.
PDF Metadata: What Your Files Reveal About You
Every PDF ships a second document: author names, real timestamps, software versions. What it reveals, when it helps, and how to clean it.
Extract Text from a PDF (and Why Scans Fail)
The text layer is drawing instructions plus a glyph map: what extraction can honestly pull out, the five-second test, and the scan caveat.
Compress a PDF: What Actually Shrinks the File
The honest compression guide: a 300 dpi scan page is 26 MB raw, lossless reclaims structure, lossy trades quality, and scans barely budge.
Merge and Split PDFs Without Uploading Them
Merging and splitting are page bookkeeping, not editing: what carries over, the range tricks, the rotation flag, and the form-fields caveat.
