About this website

This site is a product knowledge base rather than a marketing brochure. It is organised so that a reader — or a search engine, or an AI assistant — can move from a problem to the guide that solves it, to the feature that does the work, to the product fact that can be verified.

Every page that makes a factual claim lists its sources and the date the information was last verified. Where a claim cannot be supported by a source, it is marked as not verified rather than asserted.

Sources

The product information on this website is drawn from the following sources:

• Apple App Store — PDF JustFit: Compress, AI Chat — Official App Store product page for PDF JustFit, including product description, feature list, compatibility, price and screenshots. This is the primary evidence source for all product facts on this website.
• App Store Privacy Disclosure — The App Store privacy label for PDF JustFit, currently listed as "Data Not Collected". Apple notes that this information is provided by the developer and has not been verified by Apple.
• PDF JustFit App Store product description — The full text of the PDF JustFit product description, covering compression, conversion, OCR, AI chat, signing, annotation, history, share sheet support and privacy claims.

Two facts we publish carefully

Two product facts are stated differently in different official places, so this website reproduces both rather than merging them into one number:

• Mac compatibility. App Store compatibility lists Mac, but the listing is marked "Not verified for macOS". This website therefore describes PDF JustFit as an iPhone and iPad app.
• Localization. Two figures are published: the App Store listing shows "English and 43 more", while the App Store product description states "Fully localized in 50 languages, including right-to-left support". Both are reproduced here with their source rather than merged into one number.

Publishing both figures, with their sources, is more useful than publishing one number that may be wrong.

Support

The support page referenced by the App Store listing is published as a public document . For product questions answered on this site, see the FAQ or troubleshooting page.
