QBMFX PDF/A converter
Create a PDF/A-2b archival copy by rebuilding visible pages as RGB images and embedding a verified sRGB output profile and archival metadata. The local writer’s test output passed independent veraPDF conformance validation. This raster workflow preserves page appearance while discarding searchable text and interactive document objects. Check the required archival level with your recipient and preserve the original editable document. Book centers, freelancers and developers can use this free local workspace without a login or paid conversion API. Keep the original and inspect the downloaded result.
Choose your files and review the settings.
Keep originals and inspect the result before printing. File changes clear previous downloads. Heavy image and OCR work can take longer on a phone.
Using PDF/A converter
- Choose one unencrypted PDF and keep the original.
- Set raster DPI, image quality and the archival title.
- Create the PDF/A-2b copy and validate it against the recipient’s archival requirements.
Behind the result
A valid converter must enforce the selected PDF/A profile and check the produced file against its structural and rendering requirements.
Free tools for everyday work
Book centers, photocopy shops, freelancers and developers can use this workspace without a paid plan or account. Files are processed locally. Prepare website resources from offline setup before disconnecting; Urdu/OCR also needs the separate pack above.
The Windows app currently includes the original four tools. The expanded tools are available on the website; app and extension updates will be separate releases.
Answers and practical details
Archival status
An ordinary PDF, flattened scan or file with PDF/A metadata is not automatically a conforming PDF/A document.
Price and accounts
This website workflow is free without a login, subscription or paid conversion tier. Your browser supplies the processing memory and CPU.
Local file handling
Selected documents and generated results are processed on your device. QBMFX does not upload them to a conversion server or save them in a customer database. Hosting, advertising and opening external links are separate network activity.
Offline preparation
Prepare the supported website resources while connected, wait for the ready status and test the workflow before disconnecting. OCR, advanced PDF processing or fonts can need an additional local resource pack. Browser cleanup can remove saved resources.
Installed app availability
The Microsoft Store app and Edge package currently contain the original four tools. Website additions require a separate installed-package release and do not update those packages automatically.
