Unlimited PDF processing without Sejda's daily task limits.

PDF tools comparison

Sejda's PDF editing capabilities go beyond what most lightweight tools offer. The inline text editor lets you click on existing text in a PDF and modify it directly, changing wording, fixing typos, or updating information. The form filler handles interactive PDF forms with text fields, checkboxes, and radio buttons. Page manipulation tools include merge, split, extract, delete, rotate, resize, and crop. The header and footer tool lets you add consistent page numbers, dates, or custom text across a document.

File Studio focuses on the most commonly used operations: merging, splitting, compressing, converting between PDF and image formats, and removing passwords from locked PDFs. It does not include inline text editing or form filling. For users who primarily need to combine, reorganize, or convert PDFs, File Studio covers those needs effectively. For users who need to edit text content within a PDF, Sejda's editor is the more capable tool.

Both tools handle merging and splitting well, with drag-and-drop interfaces and page range controls. File Studio has no task limits, file size caps, or page count restrictions, which gives it an advantage for batch workflows and large documents. Sejda's free tier restrictions can slow you down during busy work sessions, and the desktop version, while unrestricted, costs significantly more than File Studio.

Sejda's licensing complexity is another factor worth considering. The web version and desktop version are separate products with separate pricing. If you want both online flexibility and offline processing, you would need to purchase both. File Studio simplifies this with a single product that always processes locally. There is one price, one application, and one set of features that work identically on both Mac and Windows. This simplicity extends to the user experience: you never need to check which version supports which feature or whether your subscription covers the operation you need.

Image handling

Sejda's image capabilities are limited to converting images to PDFs and extracting images from PDFs. There are no tools for converting between image formats, compressing images, resizing, cropping, or watermarking. If you need to prepare images for a website, convert iPhone photos from HEIC to JPG, or add watermarks to client proofs, Sejda cannot help.

File Studio includes a full image toolkit with format conversion, compression, resizing, cropping, watermarking, and collage creation. For users who work with both documents and images as part of their daily workflow, this eliminates the need for a separate image tool. The image features run locally with the same privacy guarantees as the PDF tools, so product photos, client work, and unreleased designs stay on your device throughout the process.

This gap becomes especially apparent in common professional workflows. An architect might need to split a large PDF blueprint, convert specific pages to high-resolution images for a presentation, resize those images to standard dimensions, and add a watermark before sharing with clients. Sejda can handle the PDF splitting but has no tools for the image processing steps. File Studio handles the entire sequence from PDF manipulation through image preparation, all within a single application and without any file leaving the user's machine.

Privacy and data handling

Sejda's approach to privacy depends on which version you use. The online version processes files on their servers, with files uploaded over HTTPS and deleted after five hours. This is standard for online tools and adequate for non-sensitive documents. The desktop version processes files entirely on your local machine, providing the same privacy benefit as File Studio.

The privacy distinction between Sejda's web and desktop versions is important. If you choose the desktop version for privacy reasons, you are paying $69.95 for local processing. File Studio provides the same local processing guarantee at $29, and includes image tools that Sejda Desktop does not offer. Both products keep files on your machine; File Studio simply does so at a lower price with a broader feature set.

For users who want the flexibility to switch between online and offline processing depending on the situation, Sejda's dual model has merit. But this flexibility comes at a higher total cost if you purchase both the web subscription and the desktop license. File Studio simplifies the decision by offering one product that always processes locally.
