Pros and cons
ApexPDF
- Genuinely free with no watermarks, no usage caps, and no signup at any point, confirmed by the $0 pricing page and multiple tool pages.
- Client-side WASM architecture means files never leave the browser, a real and verifiable privacy guarantee that server-based competitors like iLovePDF cannot match.
- Advanced settings expose optional external processing modules (PyMuPDF, Ghostscript, CoherentPDF), giving technically capable users a path to higher-quality output without switching tools.
- No independently verified user reviews on major software directories (Capterra, G2, GetApp) as of this review, making it impossible to assess real-world output quality or reliability at scale.
- The optional external processing modules (PyMuPDF, Ghostscript) require manual configuration, which is a meaningful friction point for non-technical users who may not know what those tools are or how to install them.
- No cloud storage integration, no team workspace, and no API, so any workflow that involves sharing, version control, or automation hits a hard wall.
Bra Size Calculator
- Six-measurement detailed mode captures loose, snug, tight underbust and three bust positions, giving a more considered estimate than single-formula calculators
- Separate AFAB and AMAB bust-weighting methods make this one of the few free sizing tools that explicitly addresses non-binary and transgender users
- All data stays on-device with no account required, so there is no privacy exposure at any point in the process
- No brand-specific sizing data: the tool explicitly notes that US labels vary by brand and directs users to check individual brand charts, meaning the output can still be wrong for a specific retailer even when the measurement is accurate
- Web-only with no mobile app, which is a real friction point when users are in a fitting room and need to reference their results or try-on journal on a phone
- The try-on journal is described as a local, on-device feature with no sync or export, so switching devices or clearing browser storage loses all logged fit history
Our verdict
ApexPDF verdict
ApexPDF is the right pick for anyone who handles sensitive documents and refuses to upload files to a third-party server. The tradeoff is that it is a newer, less battle-tested tool than established names, and its claim of 100+ tools has not been independently verified at depth. If you need cloud storage integration, team collaboration, or a proven enterprise track record, look elsewhere.

The best fit for someone who wants a fast, private, no-strings sizing estimate without handing over an email address or installing an app. It covers more measurement modes and sizing systems than most free alternatives, but it produces a starting size to try, not a guaranteed fit, and it has no AI, no brand-specific fit data, and no mobile app of its own. Anyone who needs retailer-specific recommendations or wants a guided fitting experience backed by a brand database should look elsewhere.
