EditPDF AI vs. Sejda
Sejda has a polished visual editor, but its free web tier stops you after three tasks an hour and processes your files on its servers. Here is the honest split, checked against Sejda's own pages.
Executive summary
The headline difference is the free tier. Sejda's free web plan is widely documented — and consistent across reviews — as 3 tasks per hour, 50 MB per file, and 200 pages per document, with no signup required. Once you hit the hourly cap you wait or pay. EditPDF AI's core browser tools have no per-task or hourly cap at all; capacity is bounded only by your device's memory and the individual tool's stated limits. That "3-tasks-per-hour wall" is common enough that a whole category of "Sejda alternative" pages exists to route around it.
The processing models are opposite. Sejda's own site describes Sejda Web as "the online browser-based tools, where you upload your documents and process them on our servers." Sejda Desktop is a separate downloadable application that "processes documents on your local computer, without uploading them to our servers" — but it is a paid install, not the free web experience. EditPDF AI's core tools — edit, merge, split, compress, sign — run in your browser on your device with no install and no account, and each AI tool states per tool what text or page image is sent to a server route.
On price and scope, the comparison is uneven and worth stating plainly. Sejda's paid plans lift the limits (unlimited documents, no hourly cap, OCR up to 100 pages, batch processing, up to 21 minutes per task, files up to 500 MB) and include the local-processing desktop app; its pricing page renders in Australian dollars (a A$8 seven-day pass and roughly A$99/year for Desktop+Web on the page checked), so the real cost in your currency varies. EditPDF AI's Pro tier is a flat $1 USD/month with no trial. Sejda's visual PDF editor is more mature for hands-on layout work; EditPDF AI covers a wider set of AI-assisted tasks and ships full JSON-LD structured data plus a curated llms.txt.
Feature by feature
| Feature | EditPDF AI | Sejda |
|---|---|---|
| Free-tier task limits | None on core browser tools — bounded only by device memory | 3 tasks per hour on the free web plan (widely documented) |
| Free-tier file / page ceiling | No fixed cap; per-tool limits stated on each tool page | 50 MB per file, 200 pages per document on the free plan |
| Core-tool processing model | Runs in your browser on your device | Sejda Web uploads files and processes them on Sejda servers (their words) |
| Local (on-device) processing option | It is the default, in the browser, free | Yes — but only via the separate paid Sejda Desktop install |
| Cheapest paid tier | $1.00 USD/month, flat | A$8 seven-day pass / ~A$99 per year Desktop+Web (their pricing page, shown in AUD) |
| Visual / hands-on PDF editor | Full browser editor; complex layout work is less refined | A mature, well-regarded visual editor |
| Batch processing & long-running OCR | Single-document workflow; OCR per page against the daily AI allowance | Paid plans add batch and OCR up to 100 pages, 21 min/task |
| Structured data (JSON-LD) & llms.txt | Full @id-linked graph and a curated llms.txt on every page | Not reviewed for this comparison |
Where each one is honestly stronger
EditPDF AI
Strengths
- No hourly or per-task limit on core browser tools — no "wait an hour or pay" wall
- On-device processing is the free default, not a paid desktop download
- Flat $1/month USD Pro with no trial and no currency-conversion step
- Full JSON-LD structured data and a curated llms.txt on every page
- A wider set of AI-assisted tasks — chat, summarise, translate, OCR, mind map, quiz, form fill
Weaknesses
- Sejda's visual editor is more polished for hands-on layout and design work
- No batch processing; long OCR jobs are metered per page against the daily AI allowance
- Newer product with a smaller track record and English only
- No installable desktop application
Sejda
Strengths
- A mature, well-regarded visual PDF editor
- A genuine local-processing option in Sejda Desktop (paid install)
- Paid plans remove limits and add batch, longer tasks, and OCR up to 100 pages
- Established product with years of operating history
Weaknesses
- Free web plan stops at 3 tasks per hour — the single most-cited complaint
- Free web tools upload your files to Sejda's servers to process them
- Pricing page shown in Australian dollars, adding a conversion step for most users
- On-device processing requires paying for and installing the separate desktop app
Verdict
If you run PDF tasks in short bursts and keep hitting Sejda's three-per-hour free limit, or you want routine work to stay on your device without paying for a desktop install, EditPDF AI's free tier goes further and its $1/month Pro is a flat USD price. If your work is hands-on visual PDF editing, or you need batch processing and long OCR jobs, Sejda's editor and paid plans are built for that in a way EditPDF AI does not fully match yet.
Does EditPDF AI have Sejda's 3-tasks-per-hour limit?
No. Sejda's free web plan is widely documented as 3 tasks per hour with a 50 MB / 200-page ceiling. EditPDF AI's core browser tools have no hourly or per-task cap — capacity is limited only by your device's memory and each tool's own stated limits — and they process files on your device rather than uploading them.
