Home / solopdfs Pro
All solopdfs tools continue to run for free in your browser. Pro adds what is saved in your account, what follows you to other devices, and working with more than 3 documents at once.
€7.00 a month, VAT included
Charged in advance from your balance. No hidden fees and no minimum term.
A top-up of €49.00 (VAT included) gives you €84.00 of balance.
The difference is a promotional bonus: it is not refundable and cannot be exchanged for cash. The minimum top-up is €7.00, VAT included.
With the free plan, you can have up to 3 documents open at once. With Pro, you can open more and apply a tool to all of them.


A workflow is a sequence of steps with their settings (rotate, number, watermark, compress…). For free, you can create, run, and export it to a file. With Pro, it stays saved in your account for your next visit. A workflow saves only settings: never passwords, keys, or documents.


My stamp imprints the image of your signature, your logo, and a line of text. It is an image, not a digital signature. Free lasts while the page is open; with Pro it is stored encrypted in your account and follows you to your other devices.


Your favorite tools, language, theme, panel width, and permission choices can follow you to other devices. Without Pro they stay only in this browser, and they still work.


Checking whether a PDF complies with PDF/A is free. Converting it, with the preset for LexNET submissions (searchable text, size, and attachments), is part of Pro. Each result honestly explains what complies and what does not.


When you download several documents as a ZIP you can add an index with their names and fingerprints, and sign it with your certificate. The recipient checks it with our verifier or with openssl commands, and checking is free.


When signing with a certificate you can ask for a time stamp from an outside authority, which proves the document existed at that moment. We always ask before sending anything, and only the document's fingerprint leaves, not the document.


Pro features remain available offline for up to 7 days after your account was last checked, for instance while traveling. After that period, you need to connect once.

The balance is in euros and has two parts: the balance you paid and, at times, a bonus. Pro costs €7.00 a month (VAT included), is charged in advance from your balance, and paid balance is spent first, then the bonus. The minimum top-up is €7.00 (VAT included), the price of one month of Pro. If upon topping up your account does not have Pro and your balance covers one month, Pro activates by itself when the payment is confirmed; with less, the balance is kept and you can add more. On renewal with less than a month of balance, what remains is charged and Pro lasts for the days it covers (thirty days to a month, rounded up). If there is no balance left at renewal, there are 7 days of grace and then the account returns to the free plan.
No. You pay on our payment provider's secure page and the balance is added once the payment is confirmed. We do not store bank details when you top up.
The balance you have paid and not spent is refunded when you close your account: you request it then, give us a bank account, and we transfer it to you, fee-free. The transfer is made starting from 14 days after closing the account or 120 days after your last payment, whichever comes later, in order to verify that the payment was correct; when closing the account we show you that date. The bonus is not refunded and is lost upon closing the account. What you have already spent on months of Pro, or on the days of Pro given with a balance below one month, is not refunded. This does not limit the rights that the law recognizes for you as a consumer.
Yes, whenever you want: the plan keeps what you already paid for until the end of the period, and then the account returns to the free plan. The free tools stay yours.
No. Documents are always processed in your browser. The account stores only small things such as your settings, your stamp or your workflows. The time stamp sends only the document's fingerprint, and only after asking you.
No. Because everything runs on your device, the limit is set by its memory and speed. Pro removes the cap of 3 documents at once, not your device's limits.
