Convert Magic vs Sejda: Which PDF Tool Has Fewer Limits? (2026)

Sejda is a well-built PDF editor with a clean interface and a deserved reputation for quality output. It's one of the better online PDF editors out there. But its free tier is governed by a set of caps that are easy to hit during real work. We tested both tools head to head to see where each one fits.

Short answer: Convert Magic is unlimited with no hourly caps or page limits. Sejda is polished but throttles the free tier to 3 tasks per hour with file and page ceilings.

Speed Comparison: Real Tests

We converted a 10.4MB PDF to Word on both platforms, five times each.

Convert Magic:

Run 1: 2.3 seconds
Run 2: 2.5 seconds
Run 3: 2.2 seconds
Run 4: 2.6 seconds
Run 5: 2.4 seconds
Average: 2.4 seconds ✅

Sejda:

Run 1: 11.6 seconds (includes upload)
Run 2: 9.8 seconds
Run 3: 13.4 seconds
Run 4: 10.2 seconds
Run 5: 12.0 seconds
Average: 11.4 seconds ❌

As with most server-based tools, the bottleneck is the network round trip, not the engine. Sejda processes files in the cloud; Convert Magic processes them in your browser, so it begins instantly and never waits on an upload.

The Sejda "Free" Reality Check

Sejda is more generous than some, but the free tier limits stack up quickly:

3 tasks per hour. Convert four files in a session and the fourth is blocked until the hour resets.
50MB file size cap. Fine for slide decks, tight for high-resolution scans.
200-page limit per document. Long reports, manuals, and legal bundles exceed this.
Hourly resets, not daily. Better than a hard daily cap, but still a stop-and-wait rhythm when you're working in bulk.

For occasional one-off edits, you may never notice. For a workday of converting and merging, you'll hit the wall.

Feature Deep-Dive

PDF Editing

This is Sejda's real strength. Its inline PDF editor — adding text, images, links, and annotations directly onto a page — is genuinely good and better than what Convert Magic offers today. If your core need is editing the contents of a PDF rather than converting it, Sejda is worth the trip.

Convert Magic focuses on fast, accurate conversion and document assembly: PDF to Word, PDF to Excel, PDF to JPG, plus merge and split.

Batch Work and Throughput

Because Convert Magic has no hourly cap, batch jobs run straight through. Drop a stack of files and convert them all without watching a counter. On Sejda's free tier, every task counts against your 3-per-hour budget, so high-volume work means waiting or upgrading.

Security and Privacy

Sejda uploads files to its servers and states they're deleted automatically after a few hours. That's standard practice and reasonably transparent. But for confidential material — contracts, financials, medical or client documents — Convert Magic's local processing means the file never leaves your device in the first place.

When to Choose Sejda

Sejda is the better pick if:

You need to edit text and elements inside a PDF, not just convert it
You want its desktop app for offline editing
You do a small number of tasks and value its polished editing UI over throughput

It's a quality tool — the limits are the tradeoff for the free tier, not a knock on the product.

Conclusion

Sejda wins on in-PDF editing depth. Convert Magic wins on everything throughput-related: no hourly caps, no page or size ceilings, instant local processing, and private-by-default handling. For converting, merging, and high-volume document work, the lack of limits is the deciding factor.

If you want unlimited PDF conversion with no hourly counter:

👉 PDF to Word — convert in 2 seconds → 👉 PDF to Excel — intelligent table extraction → 👉 Split a PDF — extract exactly the pages you need →
