Quick answer: if you’ve hit Sejda’s free limit and just need to convert, compress, merge, split or sign PDFs, Altto does it free with no hourly limit, no page cap and no upload. If you need Sejda’s in-place PDF text editor, or you’re happy to pay for a week pass, Sejda is a good tool.
Sejda’s free limits
Sejda’s own site describes its free online service as working for documents of up to 200 pages or 50 MB, with 3 tasks per hour, and some tools have lower page limits for conversions and OCR. Uploaded files are deleted automatically after 2 hours. Paid plans remove the limits: a Web Week Pass is a one-off payment for seven days, and there are monthly and annual subscriptions. Sejda also offers a desktop app that works on your computer without uploading.
How Altto is different
Altto has no hourly limit, no page cap set by us and no account. Every tool runs in your browser, so your files are never uploaded in the first place, the same privacy benefit as Sejda Desktop but without installing anything. The limit on very large files is your own device’s memory rather than a rule.

Where Sejda is the better choice
- Editing PDF text in place. Sejda’s editor lets you change existing words, add text and whiteout areas directly on the page.
- A few specialist tools. Sejda has extras such as automatic margin cropping and bates numbering that Altto doesn’t offer.
- A desktop app. If you prefer installed software, Sejda Desktop gives you its tools offline.
Where Altto is the better choice
- No waiting an hour. Process as many files as you like, one after another.
- Long documents. No 200-page or 50 MB cap from us; big files just take longer on slower devices.
- Privacy without installing anything. Nothing is uploaded, and it works on phones as well as computers.
