Merge PDF files online free, edit, compress, convert and sign documents without paying — ten tools tested, including the jobs that genuinely need Adobe Acrobat.
For most people PDF work is occasional, which means subscription pricing rarely makes sense. Start with a free browser toolkit and only pay when you genuinely need to edit text inside a scanned document or process signed contracts in volume.
Watch one thing on every free tool: the daily task limit. Most of these sites are excellent until you hit the third job of the morning, which is why we keep two of them bookmarked rather than one.
Both Smallpdf and iLovePDF merge PDFs in the browser with no install and no account. Smallpdf is the more complete toolkit; iLovePDF has the friendlier free allowance, which makes it the one we reach for when Smallpdf hits its daily limit. Neither uploads anything you should not be uploading — for sensitive contracts, use a desktop tool instead.
Editing existing text inside a PDF is the one job most free tools quietly refuse. Sejda lets you do it in the browser with three free tasks a day. PDFescape needs no account at all for annotations and form filling. Adobe Acrobat remains the only reliable answer when the document is a scan and needs OCR first.
Smallpdf handles the everyday conversions (PDF to Word, Word to PDF, and back). Convertio supports more formats than anything else we tested, though file-size limits make it an odd-jobs tool. CloudConvert goes further into audio, video and ebooks. Pandoc is command-line only and unbeatable for bulk work — five hundred Markdown files into a PDF is a single command.
Smallpdf compresses PDFs when an attachment is over a size limit. For images, TinyPNG is still the first thing we run before uploading anything to the web: noticeably smaller files, no visible difference.
DocuSign is the name your counterparty already trusts, and you are paying for the audit trail and compliance rather than for the signing interface. If you already have an Adobe Acrobat subscription, it covers e-signatures well enough for most small businesses.
For most people PDF work is occasional, which means subscription pricing rarely makes sense. Start with a free browser toolkit and only pay for Acrobat when you genuinely need to edit text inside a scanned document or process signed contracts in volume.
All-in-one PDF toolkit: compress, convert, merge, split, edit, and e-sign.
Open Smallpdf or iLovePDF, choose Merge, drop your files in and download the result. Both work in the browser with no install; iLovePDF is the more forgiving of the two when you are doing several jobs in a day.
Sejda for editing existing text in a browser (three free tasks a day), PDFescape for annotations and forms with no account. For scanned documents you need OCR, which means Adobe Acrobat.
It has a free tier with daily task limits and file-size caps. It is enough for occasional personal use; heavy users will hit the cap and either wait or pay.
Smallpdf and iLovePDF both convert PDF to Word free within their daily limits. For bulk or confidential documents, Pandoc runs entirely on your own machine.
Only if you edit scanned documents, need reliable OCR, or process signed contracts in volume. Everything else on this page can be done for free in a browser.
