The PDF tasks you can do free in your browser
Merge, split, compress, convert, sign and watermark — the everyday PDF jobs that should not need a desktop app or a sketchy upload site. Here is what each one is for.
In short
The everyday PDF jobs — merge, split, compress, convert, sign and watermark — can all be done free in a browser, with no desktop software. Because contracts and ID scans are sensitive, prefer PDF tools that are part of a platform you already trust over anonymous "upload your file here" sites.
PDFs are the format everyone sends and nobody enjoys editing. The good news: the everyday tasks — combining files, shrinking them, signing a contract — no longer need expensive software or a questionable "upload your file here" website. Here is a tour of the jobs you can knock out in a browser, and when you reach for each.
Combine and split
The two most common PDF chores are putting files together and pulling them apart. Merge when you need one clean document — a proposal plus its appendices — and split when you only need to send a few pages of a larger file.
- Merge several PDFs into one in the right order
- Split out a page range to share just what is needed
- Reorder or delete pages without rebuilding the file
Compress for email and upload
A PDF full of high-resolution scans can be too big to email or upload to a portal. Compressing it trims the file size while keeping it readable — usually the difference between "attachment too large" and "sent".
Convert to and from PDF
Sometimes you need a PDF from images, or images out of a PDF. Converting both directions covers the common cases: turning a stack of photos into a single document, or pulling a page out as an image for a slide.
- Images to PDF for receipts, scans and portfolios
- PDF to image when you need a page as a picture
Sign and watermark
Signing a PDF in the browser means you can return a contract in minutes instead of printing, signing and scanning. Watermarking stamps a document as a draft, confidential, or yours — useful before you send work out for review.
Why "in the browser" matters
The convenience is only worth it if your document is handled responsibly. The reason to prefer a trusted tool over a random free site is simple: a contract or an ID scan is exactly the kind of file you do not want sitting on an unknown server. Use PDF tools that are part of a platform you already trust with the rest of your work.
FAQ
Can I edit a PDF for free?+
The everyday tasks — merge, split, compress, convert, sign and watermark — can all be done free in the browser with CorePDF, no desktop software required.
Is it safe to use online PDF tools?+
It depends on the provider. A contract or ID scan is sensitive, so prefer tools that are part of a platform you already trust rather than anonymous free sites.
How do I make a PDF smaller to email it?+
Compress it. Compression reduces the file size — usually by shrinking embedded images — while keeping the document readable enough to send.
