PDFs are great—until you try to edit them and suddenly, your fonts are swapped, distorted, or gone. Sejda is a freemium tool with automatic font detection to help you modify the document while keeping the original typography intact.
How to Edit a PDF Without Losing Its Fonts
Sejda’s PDF Editor lets you add, delete, or modify text and images within a PDF without losing the original font. It automatically detects the text font from your uploaded document, so all you have to do is focus on your edits.
To get started, visit Sejda PDF Editor and upload your PDF file. If you’re working with a sensitive document and prefer to keep it offline, download the desktop version instead. Sejda is a cross-platform tool that is available for Windows, macOS, and Linux.
In the editor, use the text tool to highlight and modify text blocks. The top menu lets you erase, whiteout, annotate, and add media and signatures to your document. Use the little Trash bin icon to remove the unwanted pages from your PDF document.
Once you’re done, click Apply changes. You get the option to save the document to your local drive or Cloud storage. All uploads are encrypted and permanently deleted after two hours, so your files will not be stored on the Sejda servers.
Beyond basic editing, Sejda PFD Editor has other useful features that you can use. You can create and fill in forms, use Find and Replace to quickly locate and update text, add URLs, insert watermarks and shapes, and annotate the document with ease.

The 8 Best Free OCR Software Apps to Convert Images Into Text
Tired of retyping text from images? Here are some free OCR software apps that seamlessly convert images into editable text.
In addition to these core features, Sejda also offers several smaller yet handy tools allowing you to extract images, edit metadata, make the text and images greyscale, add numbers to pages, and remove all the annotations on a PDF document.
What I like about Sejda PDF editor is how clean it makes the whole process of uploading, editing, and downloading the PDF document. Simply upload, edit, and hit download. Unlike many online PDF editors, there are no sneaky signups, payment traps, or tactics that hold your edited file for ransom for a service that you occasionally use.
The free version is surprisingly generous, allowing up to three tasks per hour with documents up to 200 pages or 50MB in size. However, if you’re making extensive edits, be mindful of the time and save and download your work periodically to avoid losing progress. If you need unlimited access, premium plans start at $5/week, $7.50/month for Sejda Web, or $65/year for both Sejda Web and Desktop.
While many free PDF editors for Windows and the web offer a range of features, they often fall short in flexibility. Sejda stands out with its impressive suite of PDF management tools, particularly its automatic font detection and Workflows feature, which give it an edge over both free and paid alternatives. It’s reliable, polished, and just works.
