PDF tools that run in your browser
Short answer: For common PDF work, choose the tool that matches the job: merge files, split pages, reduce file size, convert formats, protect sensitive documents or remove hidden data. QuickMerge runs these PDF tools in your browser without uploading the document.
Every tool on this page reads your PDF in browser memory instead of uploading it to a QuickMerge server. Pick the task you need — the tools are grouped by what people usually do first, what they do to finish a document, and what they do before sharing it.
22 tools in this canonical category. Supported operations use local browser processing; see how to inspect a specific workflow.
Combine and separate pages
Start here when a document arrives in the wrong number of files.
- Merge PDF — Combine several PDFs into one file in the order you choose.
- Split PDF — Extract a page range or break one PDF into separate documents.
- Organize PDF — Reorder, rotate and delete pages, then export the result.
- Rotate PDF — Turn sideways or upside-down pages by 90°, 180° or 270°.
Change the file size or format
Use these when a PDF is too large to send, or when you need it in another format.
- Compress PDF — Reduce PDF file size so it fits an email or upload limit.
- PDF to Word — Convert a text-based PDF into an editable DOCX file.
- PDF to JPG — Save each page of a PDF as a JPG or PNG image.
- Image to PDF — Turn JPG, PNG or WebP images into a single PDF.
- HEIC to PDF — Combine iPhone HEIC photos into one PDF document.
- Text to PDF — Create a PDF from pasted or typed text.
Prepare a document for sharing
Do these last — after the pages are final — so nothing is undone by a later edit.
- Redact PDF — Find and black out SSNs, card numbers, emails and phone numbers.
- Remove PDF signature — Delete signature fields and stamp annotations from a PDF.
- Sign PDF — Draw, type or upload a signature and place it on any page.
- Type on PDF — Add text anywhere on a PDF, then flatten it into the page.
- Fillable PDF — Place form fields on a PDF, then save it fillable or flatten it.
- PDF metadata — View, edit or remove the author, software and timestamp fields.
- Watermark PDF — Stamp a diagonal text watermark across every page.
- Resize PDF — Change page dimensions between A4, Letter and custom sizes.
- Remove PDF watermark — Find and delete watermark layers and stamps that sit on top of the page.
- Add page numbers — Number every page and choose the position and format.
- Protect PDF — Add a password using real AES-256 encryption.
- Unlock PDF — Remove a password from a PDF when you already know it.
Which tool for which problem
Choose a tool by the change you need: arrange pages, reduce bytes, extract content, or prepare the document for sharing. The groups above link to the relevant controls and limitations.
Organize, rotate, merge and split change page arrangement. Compress aims to reduce bytes; splitting may help when only a subset is needed. Word and image exports serve different receiving applications, with limitations described on each tool.
The fourth question is the one people skip. Redaction and metadata are the tools that decide whether a document is safe to send, and both belong at the end of the process rather than the beginning.
The order that avoids rework
Finish the page set before you finish the document. Reordering, deleting and rotating pages should all be settled first, because page numbers stamped before a reorder no longer match, and a watermark applied before a merge appears on only part of the result.
Protection goes last. Encrypting a PDF makes it unreadable to every other tool here, so a password added early means removing it again before any further edit. Compress before protecting too — an encrypted file cannot be recompressed without being decrypted first.
Why these run in the browser
Every tool on this page reads your file in browser memory rather than uploading it. For PDFs that distinction is unusually concrete: contracts, invoices, medical letters and identity documents are exactly the files people are asked to hand to a web service, and exactly the ones that should not be.
There is no daily server quota or account, but individual tools enforce stated browser-safety limits and very large or complex documents still depend on your device. A file that is comfortable on a laptop may exhaust memory on an older phone. Check the limit shown by the tool before you begin, and use the privacy verification steps to inspect network behavior yourself.

Questions people ask
Do I need an account to use these PDF tools?
No. The PDF tools on this page work without an account, without a subscription and without a watermark on the output.
Is there a file size limit?
Yes. Limits vary by tool and are shown in the interface; they protect the browser from running out of memory. Large or complex PDFs can also be slow on older phones, so check the stated limit before starting and use a desktop for demanding files.
Which tool should I use first when a PDF is too big to email?
Start with Compress PDF. If the file is mostly scanned pages, compressing the images inside it saves the most space. If it is a long document you only partly need, Split PDF is usually a bigger win than compression.
Do these PDF tools work on a phone?
Yes, in a mobile browser. Processing uses your device, so large or complex documents are noticeably slower on an older phone than on a desktop. If a tool stalls on a big file, try the same file on a computer before concluding it failed.
Which tool do I use to make a PDF smaller for email?
Start with Compress PDF. If the document is mostly scanned pages, compression saves the most because the images inside dominate the file size. If you only need part of a long document, Split PDF is usually a bigger reduction than compression.
Can I edit the text inside a PDF here?
Not directly — these tools work on pages, security and structure rather than rewriting body text. To change wording, convert to Word with PDF to Word, edit there, and export back to PDF.
Why can I not compress or merge my PDF?
The most common cause is that the file is password-protected. Encrypted PDFs cannot be read by the other tools until the password is removed with Unlock PDF.
Is there a limit on how many files I can process?
No. There is no account, no daily cap and no queue, because nothing is uploaded and there is no server metering usage.
