A Smallpdf alternative with no upload step

Smallpdf is one of the two names most people reach for first in this category, and it earned that position. It is polished, it handles an unusually wide range of tasks, and it works predictably across devices.

The difference described here is narrow and specific: where the file is processed. That narrowness is deliberate. A comparison that claimed a small new site beats Smallpdf at everything would not be worth reading.

What Smallpdf does better

• Conversions. Word, Excel, PowerPoint, and back again, plus several image formats.
• OCR. Making a scan searchable, which is CPU-heavy and belongs on a server.
• E-signature workflows. Requesting signatures, tracking status, collecting from multiple parties — workflow, not a single signature image.
• AI-assisted features. Summarising and chatting with document contents.
• Breadth and polish. More tools, more years of edge cases handled.
• Localisation. Many interface languages.

If any of those are your task, Smallpdf is the better tool and this page will not pretend otherwise.

Where the two differ

	Smallpdf	PDF Kept
Where files are processed	Their servers	Your browser
Upload required	Yes	No
Works offline after first load	No	Yes
Account required	For some features and limits	Not offered
Task or file limits	Daily caps on the free tier; size limits	No task counter or daily quota; 30 files and 500 MB per file, to keep the browser responsive
Word / Excel / PowerPoint conversion	Yes	No
OCR	Yes	No
E-signature workflows	Yes	Single signature only
Interface languages	Many	English

The one difference that compounds

Every claim about a server-side tool’s handling of your file — encryption in transit, deletion windows, access controls — is a statement about a system you cannot inspect. That is not an accusation. It is just the nature of a service.

Local processing moves the question instead of answering it. There is no retention window to reason about because there is no copy to retain.

This is worth what it costs only if the document is sensitive. For a lecture handout, the convenience of a broader toolset wins. For a document with someone’s name, address, diagnosis or salary in it, the calculus changes — and it changes regardless of how trustworthy the operator is.

Check it in thirty seconds

Any claim about where processing happens is verifiable, so verify it rather than believe either page.

1. Open the tool. Press F12, choose the Network tab, enable Preserve log.
2. Perform the operation on a PDF.
3. Inspect the requests.

A server-side tool must transmit the document, so a request will carry it — a POST body comparable in size to the file. A browser-only tool produces page assets and nothing resembling the document.

Run this on both products. The result does not depend on anyone’s marketing copy.

The free tier question

Both products are free to use, and “free” means different things in each case.

Smallpdf’s free tier grants a limited number of tasks per day or per period. That is a coherent business model for a server-side product: every task consumes CPU and bandwidth that someone pays for. Once the allowance is used, the choice is to wait or to pay.

A browser-only tool has a different cost structure. The processing runs on the visitor’s own machine, so there is nothing to meter — which is why this site has no task counter, no daily reset, and no account. The trade is scope: fewer tools, because only tasks that can run in a tab are included.

Neither model is dishonest. They follow from the architecture, and knowing which one you are inside explains the limits you hit.

What you give up here

• No Word, Excel or PowerPoint conversion. Deliberately not offered.
• No OCR. Out of scope for a browser tab.
• No signature workflow. You can place a visible signature; you cannot send a document for signature and track it.
• No AI features. No summarising, no chat.
• English only.
• A 30-file, 500 MB-per-file ceiling per operation, and no way to buy past it. These are guard rails for the browser rather than a quota, but they are real limits: a 500 MB scan is a server’s job.

When to choose which

Choose Smallpdf for conversions, OCR, multi-party signing, non-English interfaces, or any file large enough to strain a browser tab.

Choose PDF Kept for the everyday organising and optimising tasks — merge, split, compress, delete pages, add page numbers, watermark, convert images — on a document you would rather keep local.

Both is a legitimate answer. Nothing here requires you to pick a side.
