Sejda alternative with no upload and no task limits
Sejda is a capable PDF editor that offers both a web app and a desktop app, and it is popular for merging, editing and filling forms. Searches like "merge pdf online free sejda" show how often people start there.
If you are looking for a Sejda alternative, the common motivations are limits on free use and not wanting to upload a file. MergeDoc covers the everyday tasks locally in your browser: merging, reordering pages with thumbnails, cropping margins and filling AcroForm fields.
It is not a full PDF editor, so read the sections below on what it does not do.
Why people look for a Sejda alternative
Free-use caps
Online PDF editors typically limit file size, page count or the number of tasks per hour for free users. Hitting that wall mid-job is the usual trigger for searching.
You do not want a copy on a server
Even services that delete files after a set time still receive them. If a file is private, not sending it is the simplest policy. See merge PDF without uploading.
You only need a few operations
If your work is merge, reorder, crop and fill, a lightweight page that does exactly that can be faster than opening a full editor.
Large files that time out
Uploading a several-hundred-page scan on a slow connection often fails halfway. Processing in the browser removes the upload leg entirely, so the only wait is your own computer working through the pages.
A quick form fix before a deadline
Rental applications, school forms and tax paperwork tend to arrive as fillable PDFs the night before they are due. Filling fields locally takes a minute and needs no account or email confirmation first.
Sejda vs MergeDoc, side by side
| Sejda | MergeDoc | |
|---|---|---|
| Where your files go | Web app typically uploads files to servers; the desktop app processes locally. | Always in your browser. No upload path exists. |
| Sign-up | Core tasks typically work without an account; check their current terms. | No accounts at all. |
| Usage limits | Free web use is typically limited per task or per hour. | No limits from us beyond browser memory. |
| Watermark | Free output is typically clean. | Never added. |
| Offline use | Desktop app works offline; web app needs a connection. | Processing works offline once the page is loaded, but there is no installable app. |
| Speed on large files | Web version adds upload time; desktop avoids it. | No transfer time; speed depends on your device. |
| Editing depth | Edit existing text, add and move text and images, OCR, and more. | No text editing of existing content. Page-level operations, forms, watermark, sign and redact boxes. |
| Form filling | Fills forms and typically lets you add free-placed text fields. | Detects real AcroForm fields and fills them, with an optional flatten step. Cannot add text anywhere on a flat scan. |
When Sejda is still the better pick
- •You need to edit existing text in a PDF or add text anywhere on the page. We only fill genuine form fields.
- •You want OCR on scanned documents.
- •You prefer a desktop application that works fully offline and can handle batches.
- •You need to fill a form that has no real fields, such as a flat scan, where free-placed text is required.

Frequently asked questions
- Is there a Sejda alternative that works in the browser without uploading?
- MergeDoc does. All processing happens in your browser tab and nothing is sent to a server.
- Can MergeDoc edit text inside a PDF?
- No. It works at page level and on form fields. For rewriting existing text you need a full PDF editor.
- How do I reorder pages before merging?
- Merge first, then open the result in [Reorder PDF](/reorder), or follow the [rotate and reorder pages guide](/blog/rotate-and-reorder-pdf-pages).
- Will fill form work on any PDF?
- Only on PDFs that contain real form fields (AcroForm). If your PDF is a flat scan with no fields, the tool will find nothing to fill.
- Does flattening a filled form matter?
- Flattening bakes the typed values into the page so they cannot be changed afterwards. Leave it off if the recipient needs to edit the fields.
- Is there a page limit?
- We do not set one. Very long documents may be slow depending on your device.
- Can I add free text to a flat scanned form?
- Not at present. Fill PDF Form works with real form fields only, so scans without fields need a full PDF editor that can place free text.
