Best PDF converter

There is no best PDF converter, because converting to Word, to Excel, to images and from images are four different problems with four different winners. Pick by the format pair you actually have. This page splits the ranking that way, and says plainly which pairs pdfpix does not handle at all.

Why one winner is the wrong answer

PDF to Word needs paragraph reconstruction. PDF to Excel needs table structure. PDF to image needs a renderer and resolution control. Image to PDF needs page layout. A tool can be excellent at one and useless at the next, and most rankings hide that behind a single score.

So decide the pair first. Everything else, price, interface, account requirements, matters less than whether the tool was built for the conversion you are doing.

PDF to Word and PDF to Excel

pdfpix has no PDF to Word tool. Its PDF to Excel tool handles native-text tables and keeps selected tables in separate checked worksheets. Acrobat is the reference for both office formats at 19.99 US dollars a month on an annual commitment, checked 20 August 2026. Sejda also reads scans within its free page and hourly limits.

PDF24 offers both free, funded by advertising, and processes on its servers. The Excel roundup covers the table case, which is the one that goes wrong most often.

PDF to image

This is a rendering job, not a conversion job, and the only setting that matters is resolution. The pdfpix exporter takes 96, 150 or 300 dots per inch exactly, writes JPG or PNG, names files page-001 onward, and zips them when there is more than one.

iLovePDF and PDF Candy both do it with presets instead of numbers, on their servers. The JPG roundup ranks this pair on resolution control.

Images to PDF

The simplest pair and the one most often done badly, because tools resample your pictures without asking. The pdfpix builder detects JPG and PNG by magic bytes. HEIC to PDF decodes HEIC and HEIF locally. Both preserve pixel dimensions and offer A4 or Letter with margins of none, narrow or standard.

Free suites all offer this too. What differs is whether the output is the size you expect. If a converted photo PDF comes back far smaller than the sum of its images, something downsampled them.

Office documents and everything else

pdfpix does not convert Word or PowerPoint files and does not turn Excel files into PDF. Its PDF to Excel tool is limited to native-text tables. If you still have the source file, exporting to PDF from the application that made it produces a better result than any converter, because nothing has to be reconstructed.

For the cases where you only have the PDF, the free suites cover the long tail. PDF Candy publishes a thirty five tool desktop build for Windows that works offline, and TinyWow covers formats far outside PDF entirely. Online2PDF accepts 150 megabytes per file and thirty files at once, Soda PDF covers the office pairs without printing a price, and DocFly allows three free documents a month.

Questions people ask

Is there one best PDF converter for every format?
No. PDF to Word, PDF to Excel, PDF to image and image to PDF are four different problems. Acrobat leads the office pairs, browser tools handle images well, and no single product wins all four.
Which conversion loses the most formatting?
PDF to Word and PDF to Excel, because both have to rebuild structure a PDF never stored. The file holds positioned glyphs, so paragraphs, tables and columns are all inferred from spacing and can be inferred wrongly.
Should I convert or just export the pages as images?
If you only need to read, show or paste the pages, export images. It loses nothing and never mangles layout. Convert only when you have to edit the words or calculate with the numbers.
Do converters keep hyperlinks and bookmarks?
Often not, and few of them say so. Check one link and one bookmark in the output before you send it. Losing navigation is the most common silent failure in a conversion that otherwise looks correct.
