Adobe created the PDF format, and Acrobat is still the reference tool for working with it. DocPro is a much smaller web app. This is a comparison from DocPro's side, so we have stuck to what Adobe states on its own pages and we say plainly where Acrobat is stronger, which is in several places. Details are as of October 2026.
The short version
- Choose Adobe Acrobat when you need to edit existing text and layout, redact, build forms, compare versions, use OCR with full editing or apply certificate-based signatures.
- Choose DocPro when the job is everyday (merge, split, compress, convert, OCR, protect) and you want the file to stay on your device without paying or signing in.
What "Acrobat online" means
Adobe offers free online PDF tools on its website, and separately sells Acrobat subscriptions with desktop, web and mobile apps. Acrobat Reader is free for viewing. The comparison below treats the free online tools and the paid plans separately because they differ a lot.
Where files go
Adobe's help page says files you use in the online tools are uploaded to Adobe Document Cloud. If you sign in and save or share a file it is stored there, and if you do not, Adobe says it deletes the file from its servers a short time after use. Adobe's privacy policy says cloud content is stored on its servers and may be analysed using techniques such as machine learning, subject to opt-out rights. Read the current policy for the details that apply to you.
DocPro processes files in the browser and does not upload them. There is no copy on a server, so no retention rules or opt-outs are needed. This difference is a design choice, not a judgement on Adobe's security, which is a large company with a mature security programme.
Free limits
Adobe's help page says most online tools accept PDFs up to 100 MB, and Compress PDF up to 500 MB. Without signing in you get one free transaction. Signed in, you can fill, sign, share and comment for free, and a limited number of further transactions per week, with caps such as one file compressed and one file converted every 24 hours. Heavier use is expected to move to a paid plan.
DocPro has no per-day counter on its free tools. Sign PDF and the signature vault are the exception, as part of DocPro Pro at A$5.99 a month after a 7-day free trial.
Editing power
This is where Acrobat clearly leads. Acrobat Standard covers creating, editing, converting and organizing PDFs, editing text and images, and e-signature collection. Acrobat Pro adds OCR to editable text, redaction, web forms and version comparison, according to Adobe's pricing page. Prices vary by plan and billing term, so look at the pricing page rather than relying on a number written here.
DocPro cannot edit existing text, redact, build forms or compare documents. It can annotate on top of pages (pen, highlighter, text), reorder or delete pages, add watermarks and page numbers, crop, flatten, convert and run OCR. For quick fixes that is often enough, but for rewriting a contract line or removing a name from a document properly, Acrobat or a similar editor is what you need.
Signatures
Acrobat supports certificate-based digital signatures: you use a digital ID, can certify a document and add timestamps, and the signature shows whether the file changed after signing. Adobe's help pages describe support for PAdES and other standards. This is the right tool when a regulation or counterparty requires a verifiable signature.
DocPro's Sign PDF places an image of your signature, like signing a printout. It is not a certificate-based signature, and it needs DocPro Pro. It is fine for forms and routine paperwork, but it does not give the evidence trail that Acrobat Sign or a certificate does. Our guide to signing a PDF on your phone explains the difference.
Who each one is for
A freelancer who mostly merges invoices and shrinks scans before emailing them will rarely use more than a handful of Acrobat's features, so a free on-device tool may do everything they need. A law firm, a finance team or an accountant that edits documents, redacts sensitive text and needs signatures that can be verified will use Acrobat's advanced features daily, and the subscription pays for itself.
There is also a middle case: someone who needs one advanced job now and then. For that, many people use a free tool for the routine work and borrow time on a full editor only for the exceptions, rather than subscribing all year.
Apps
Adobe says its paid subscriptions include the Acrobat Reader and Acrobat Scan mobile apps. DocPro has no desktop app. The web app can be installed as a PWA and works offline after a first visit. The Android app is coming soon and has not been released.
Bottom line: which should you pick?
If your work involves legal documents, contracts that need verifiable signatures, redaction, or restructuring existing PDFs, Acrobat is the better choice and worth paying for. If you mostly need to combine, split, shrink, convert, protect or extract text from files, and you would rather not upload them or create an account, DocPro is a simple fit. Many people use both: DocPro for private everyday jobs, Acrobat when the job demands it.
Frequently asked questions
Is Adobe Acrobat online free?
Some tools can be tried free, with one transaction without signing in and limited use after signing in. Full features need a paid Acrobat subscription. Check Adobe's pricing page for current plans.
Does Adobe upload my PDF when I use the online tools?
Yes. Adobe says files are uploaded to Adobe Document Cloud and, if you do not save them, deleted from its servers a short time after use. DocPro does not upload files.
Can DocPro do certificate-based digital signatures?
No. DocPro places an image of your signature on the page. For certificate-based signatures, use Adobe Acrobat or another tool that supports digital IDs.
