The details
Cost: no comparison
Adobe Acrobat costs $13 per month for the standard plan and $23 per month for Acrobat Pro. It's also usually included in Creative Cloud subscription plans. Compared with Adobe Acrobat Online for basic PDF conversions such as compressing and merging, ConvertYard offers the same conversions (to Word documents, etc.) needed regularly by most people, 100% free of charge. There's no need for Adobe Acrobat Online if you only need to occasionally compress a PDF or convert it to an editable Word document.
Privacy
Adobe Acrobat Online uses its cloud server to upload your file in order to process it. Adobe processes this securely, backed by enterprise security and compliance certifications that many other companies can only dream of. ConvertYard takes the opposite approach. The WebAssembly library required to convert your documents is run on your CPU in your browser. There are no network requests made with the file data. This has huge implications for documents that are converted under NDA, for documents that contain patient data, or for lawyers who work with large amounts of legal material online.
Where Adobe is genuinely better
Adobe Acrobat Online offers PDF editing capabilities like inline text editing, image replacement, and advanced form creation, as well as e-signatures using Acrobat Sign. This, along with enterprise-level compliance features like FedRAMP, SOC 2, and HIPAA BAA support with the enterprise plan, as well as deep Microsoft 365 integration, makes Adobe the best choice for professional PDF work that extends beyond simple file conversion.
Using both
The best approach is to use ConvertYard for most of your tasks, where you save time and money with the free no-upload workflow. Use Adobe Acrobat Online for the special cases — PDF editing, e-signatures, richer annotations, complex form work — where Adobe uniquely solves the problem for you.
Verdict
If all you need to do is compress PDFs, convert PDFs to editable Word documents, merge documents, and run Optical Character Recognition (OCR) on PDFs, then use ConvertYard to get these tasks done quickly, free, and without uploading your files to remote servers. If you need to edit PDFs, sign PDFs electronically, work with rich PDF annotations, or work within complex PDF forms, and require enterprise-level compliance within your organization, then use Adobe Acrobat — the subscription is well worth it for these unique and powerful capabilities.
Common questions
Is Adobe Acrobat Online the same as the desktop app?
No. The online version of Adobe Acrobat (acrobat.adobe.com) runs in your browser and uploads your PDF to Adobe's cloud for processing. This offers a limited set of features compared to the full-fledged application, which you can download for free as a trial. After the trial, it costs $23/month or is included in Creative Cloud.
Does Adobe Acrobat upload my files?
Yes. Adobe Acrobat Online processes the data in Adobe's cloud on your behalf to create the result that you download. Adobe handles the security of your data in their enterprise-quality environment, but that does mean your file is uploaded to be processed in the cloud. Processing in ConvertYard is done entirely within your browser using WebAssembly, so there is no upload, no server involved, and no Adobe account required.
Why would I use ConvertYard when Adobe is the industry standard?
ConvertYard's PDF compression uses MuPDF to produce a compressed PDF for free (for everyday PDFs like office documents and scanned PDFs). Adobe's more advanced compression (for PDFs with embedded fonts and many vector graphics) can lead to slightly smaller files for complex documents. In most cases, the difference in file size is not significant. ConvertYard is best for free and private basic tasks (compression, converting PDFs to Word, merging or splitting documents). Adobe is best for advanced tasks like rich annotating, e-signing, complex form creation, and advanced redaction.
How does ConvertYard compare to Adobe for PDF compression quality?
ConvertYard's PDF compression uses a hybrid approach. The PDF structure is rewritten with pdf-lib, rendering and object-stream packing are done with MuPDF, and downsampling and re-encoding of embedded images is handled by a custom worker pool. Adobe can compress scanned PDFs much smaller because it ships with JBIG2 and JPEG2000 encoders. For common office documents, however, the difference in size is usually not noticeable.
Can I use ConvertYard and Adobe together?
Yes. Many people use ConvertYard for the majority of their free, private PDF processing (compression, convert to Word, merge, split). They use Adobe Acrobat for its unique features like rich annotation and e-signatures. The two tools fill very different roles in PDF work.
