PDFbolt offers 32 free online PDF tools. Each tool below opens in your browser — no install and no account. Most tools process your file on our server for a single job and remove it afterward; Sign, Redact, and Unlock run entirely in your browser.
Merge, split, reorder, and remove pages.
Combine multiple PDFs into one file.
Merging PDFs is the quickest way to turn several separate documents — contracts, scanned receipts, chapters, or reports — into a single file that is easy to email, print, or archive. Instead of attaching five PDFs, you send one.
Split a PDF into separate files by page or range.
Splitting a PDF lets you take one large document and carve out exactly the pages you need — a single signed page, one chapter, or a range you want to send on its own.
Delete selected pages from your PDF.
Scanned documents often pick up blank pages, cover sheets, or duplicates. Removing pages lets you delete those by number and keep everything else exactly as it was.
Save chosen pages as a new PDF.
Extracting pages is for when you want to keep just part of a document — a single form, an invoice, or a few pages from a long report — as its own PDF.
Change the order of pages in a PDF.
Sometimes pages end up in the wrong order — a scan goes in backwards, or an appendix needs to move to the front. Organizing a PDF lets you set a new page sequence.
Turn photos and scans into PDFs.
Create a PDF from photos or uploaded images.
Phone photos of documents and receipts are easy to capture but awkward to share. Scan to PDF gathers those images into one clean PDF that opens the same on every device.
Make files smaller and fix common PDF problems.
Reduce file size while keeping readable quality.
Large PDFs bounce off email limits, upload slowly, and fill storage. Compressing a PDF reduces its size — mostly by optimizing images — so it stays easy to share while remaining clear enough to read and print.
Fix PDFs that will not open or look corrupted.
A PDF can become unreadable after an interrupted download, a storage error, or a bad export. Repairing the PDF attempts to rebuild its internal structure so the content becomes accessible again.
Make scanned PDFs searchable (coming soon).
A scanned page looks like text but is really a picture, so you cannot search or copy from it. OCR (optical character recognition) reads the image and adds a hidden, selectable text layer.
Coming soon — visible in the directory but not runnable yet.
Create PDFs from images, Office files, and HTML.
Turn PNG, JPEG, HEIC, GIF, WebP, BMP, or TIFF images into one PDF.
Converting images to PDF is the easiest way to package pictures — photos, screenshots, scanned forms, or design exports — into a single document that prints predictably and opens anywhere.
Convert Word (.doc, .docx) to PDF.
Word files can shift their layout from one computer to another. Converting to PDF locks the formatting in place so the document looks identical for everyone who opens it.
Convert PowerPoint (.ppt, .pptx) to PDF.
Sharing a slide deck as PDF means recipients can view it without PowerPoint, on any device, with the layout exactly as you designed it.
Convert Excel (.xls, .xlsx) to PDF.
Converting a spreadsheet to PDF freezes the data exactly as it is, producing a read-only document that is perfect for reports, invoices, and approvals.
Turn HTML into a PDF.
Converting HTML to PDF is handy for saving web content, invoices, receipts, or templated pages as a fixed document instead of printing a messy webpage.
Export PDFs to images, Office formats, CAD (DXF), and PDF/A for archiving.
Save each page as a JPG image.
Turning PDF pages into JPG images is useful when you need pictures rather than a document — for slides, thumbnails, website graphics, or pasting a page into another app.
Export to Word .docx (works best on simple, text-based PDFs).
Converting a PDF back to Word gives you an editable .docx you can rework — fix a typo, update figures, or reuse the text elsewhere.
Export to PowerPoint .pptx.
Converting a PDF to PowerPoint is useful when you have a deck shared as PDF and need to edit or re-present it. Each page becomes a slide you can adjust.
Export to Excel .xlsx.
When financial statements or data tables arrive as PDFs, retyping them is slow and error-prone. Converting to Excel pulls the tabular content into a .xlsx file so you can sort and total it.
Convert to PDF/A for long-term archiving (checked when validation is available).
PDF/A is a version of PDF designed for long-term preservation: it embeds everything the file needs to display correctly years from now, which is why archives often require it.
Export each page as its own AutoCAD DXF file (R2010), delivered in a zip.
CAD drawings are frequently shared as PDFs, but to edit them you need a real CAD format. Converting to DXF turns the vector geometry in a PDF into an AutoCAD-compatible drawing you can modify.
Replace text, rotate pages, add numbers, watermarks, and more.
Find and replace text in a PDF without retyping the whole document.
Fixing a typo or updating a date in a PDF usually means going back to the source file — unless you can edit the text directly. Replace text searches the document and swaps words while the file stays a real, selectable PDF rather than a flattened image.
Rotate pages 90°, 180°, or 270°.
Scans and photos often come out sideways or upside down. Rotating pages turns them to the correct orientation so the document displays and prints the right way up.
Add page numbers to the header or footer.
Page numbers make long documents easier to navigate, reference, and print in order. Adding them to a PDF is far simpler than editing the source and re-exporting.
Add a text watermark across your pages.
A watermark labels a document at a glance — “DRAFT”, “CONFIDENTIAL”, or your company name — and discourages unauthorized reuse.
Trim margins or crop to a smaller area.
Cropping removes unwanted margins or focuses each page on a smaller region — useful for trimming scanner borders, removing whitespace, or fitting content for printing.
Update title, author, and other document properties.
Every PDF carries metadata — the title, author, subject, and creating application — that shows up in file managers, search results, and document libraries.
Work with fillable PDF forms.
Fill in form fields or flatten them into the page.
Fillable PDF forms are convenient until you need to lock in the answers or share a clean copy. This tool lets you keep the editable fields or flatten them so the values become part of the page.
Passwords, signatures, redaction, and comparison.
Remove password protection when you know the password.
A password on a PDF is helpful until it becomes a hassle to open the file every time. If you know the password, unlocking removes that protection and any printing or copying restrictions.
Add a password to open or change the file.
Sensitive documents should not be readable by anyone who happens to receive the file. Protecting a PDF with a password encrypts it so only people who know the password can open it.
Place a drawn signature on the page.
Printing a document just to sign and rescan it is slow and wasteful. Signing a PDF lets you draw your signature and drop it exactly where it belongs, right on the page.
Cover sensitive areas with black boxes.
Before sharing a document publicly or in a filing, you often need to hide names, account numbers, or other private details. Redaction covers those areas with solid black boxes.
See how two PDFs differ in text and layout.
When you have two versions of a contract, report, or design, finding what changed by eye is tedious and error-prone. Comparing PDFs highlights the differences so you can review edits quickly.
