Can mypdf compress a PDF to a specific size like Smallpdf Pro?

Yes. Choose Target size on the compress tool, enter a number in KB or MB, and each quality pass runs until the output fits. If the target cannot be hit without pushing the pages below readable resolution, you get the smallest legible file and a clear explanation rather than an unusable one.

Is there a daily limit on mypdf?

No. A limit only makes sense when each file costs the operator money to process. Your device does the work here, so there is nothing to ration.

What does Smallpdf do that mypdf cannot?

Signature request workflows with tracking, cloud storage sync, team management, and server-side OCR quality. If you need any of those, Smallpdf is the better fit and we would rather say so than pretend otherwise.

How do I verify that nothing is uploaded?

Open your browser devtools, switch to the Network tab, and run any tool. You will see no request carrying your file. You can also disconnect from the internet after the page loads and keep working.

Smallpdf alternative: no upload, no document cap

Smallpdf is a polished product with a clear business model: free use is metered, and a subscription removes the meter.

That is a fair trade if you are happy for documents to be processed on their infrastructure. mypdf answers a different question — what if the file simply never moved?

Compression, conversion and page editing all run in your browser, which removes both the upload and the reason to count your documents.

Feature	mypdf	Smallpdf
Where the file is processed	Your browser	Uploaded to Smallpdf servers
Free usage limit	None — no counter exists	Free tier is metered; a subscription lifts it
Sign-up	Not possible — there are no accounts	Required for most sustained use
Watermark on output	Never, unless you add one	No watermark on standard tools
Compress to an exact target size	Yes — name a size and passes run until it fits, or it tells you why it cannot	Preset compression levels
E-signature workflow	Visual signature only, no request-and-track flow	Full e-sign requests with tracking
Team and storage features	None	Team plans, cloud storage, sync

Where Smallpdf is better

A real e-signature product: send a document, track who signed, keep an audit trail. Our Sign PDF only places a signature image.
Cloud storage and team accounts, so a document can follow a workflow across people.
Server-side OCR trained on more material than a browser WASM engine can carry.
Customer support with an SLA, which matters for business use.

Where mypdf is different

No document counter, because nothing is metered on a server we pay for.
Target-size compression that reports honestly when your number is not reachable, instead of returning a blurry file and calling it done.
Everything keeps working with the network off after you install it.
Metadata stripping and PII redaction are first-class tools, not an afterthought.

Which to use

Pick Smallpdf if you want e-signature workflows, cloud storage sync and a support contract. Pick mypdf if you want unmetered local processing on files you would rather not upload.
