About this app
FontPlop is a free, private font viewer and tester that runs entirely in your browser. Drop in TTF, OTF, WOFF or WOFF2 files to see every glyph, test your own text, and check OpenType features, languages and metrics. Files never leave your device. It also includes a webfont generator, font comparison, a kerning game, and text-style generators. No sign-up required.
Key features
- 1Local font viewer: drop TTF, OTF, WOFF, or WOFF2 to inspect every glyph, metrics, OpenType features, variable axes, and language coverage — files never leave the device.
- 2Webfont generator: convert TTF/OTF to WOFF2 and WOFF with @font-face CSS output.
- 3Font comparison and kerning game: overlay two fonts, compare metrics, get fallback CSS, and test your eye against the designer's spacing.

Scout Review
Written by AI from measured evidence, scored out of 100.
FontPlop is a free, browser-based font viewer and tester that does exactly what it says with no sign-up and no upload. The design is clean and typographic, usability is near-frictionless, and speed is genuinely exceptional (100/100 Lighthouse). Security is solid but missing a few headers, and accessibility is strong save for a contrast issue. Growth potential is real thanks to a privacy-first wedge and a broad tool bundle. It's a competent, well-built tool that punches above its weight for an indie project.
Measure by measure
Usability
78Zero-friction onboarding: drop a file or click 'Try Inter' and you're inspecting glyphs in seconds. The five-step walkthrough, FAQ, and clear tool taxonomy make it genuinely easy to learn without docs.
Design
74Clean, typographic-first layout that practices what it preaches. The drop zone is the hero, tool cards are consistently styled, and the monospace accents fit the subject. Not flashy, but confident and coherent.
Speed
88Lighthouse 100/100 on both mobile and desktop, LCP 902ms, CLS 0, TBT 0ms. Client-side font parsing keeps the server light. This is about as fast as a web tool gets.
Security
64HTTPS with HSTS, SPF, DMARC, and sensible headers. The privacy model is architectural — fonts never leave the browser. Missing CSP, frame protection, and Permissions-Policy keep it out of the top band.
Accessibility
80Lighthouse 96/100 with one failing audit: insufficient color contrast. Semantic structure and a JS fallback message are present. No published WCAG statement, but the automated baseline is strong.
Growth
62Real problem, specific segments, and a privacy-first wedge that Font Squirrel and Google Fonts don't cover. The generator bundle widens the funnel. Early-stage, but the idea has room.
Improvement areas
- Security headers: missing CSP, frame protection, and Permissions-Policy leave 4 of 12 checklist points on the table.
- Accessibility: one failing Lighthouse audit (color contrast) undercuts an otherwise strong 96/100 score.
- No published WCAG statement or accessibility page to back up the automated score.
Design & Usability
FontPlop's design is restrained and purposeful: the drop zone is the hero, tool cards are consistently styled, and the monospace accents fit the subject matter. Usability is where it shines — no sign-up, no gate, just drop a file or click 'Try Inter' and you're inspecting glyphs in seconds. The five-step walkthrough and FAQ preempt common errors, and the tool taxonomy (viewer, webfont generator, compare, OpenType, kerning game) is clear enough that you never wonder where to go next. It's not a flashy product, but it's a confident one that respects your time.
Speed & Security
Speed is exceptional: Lighthouse 100/100 on both mobile and desktop, LCP 902ms, CLS 0, TBT 0ms. Client-side font parsing keeps the server payload minimal, and the site loads faster than most competitors' landing pages. Security is solid but not airtight — HTTPS with HSTS, SPF, DMARC, and sensible headers are all present, and the privacy model is architectural: fonts are read locally and never uploaded. But missing CSP, frame protection, and Permissions-Policy leave 4 of 12 checklist points on the table. For a tool handling confidential client fonts, those headers are worth tightening.
Accessibility & Growth
Accessibility scores 96/100 on Lighthouse with a single failing audit: insufficient color contrast — ironic for a font tool, and worth fixing. Semantic structure and a JS fallback message are present, though there's no published WCAG statement. Growth potential is real: FontPlop targets three distinct segments (type designers, front-end devs, social content creators) with a privacy-first wedge that Font Squirrel and Google Fonts don't cover. The generator bundle widens the funnel, and the domain age (~1.9 years) suggests early-stage but active development. The idea has room; execution will decide how far it goes.
Conclusion
If you inspect fonts regularly — or just want to check a client's font before you ship it — FontPlop is the fastest, least annoying way to do it in a browser. It's not trying to be FontForge or Google Fonts; it's trying to be the tool you reach for when you need to look at a font right now. On that, it delivers.
Suggestions for improvement
- Add a Content-Security-Policy and frame-ancestors directive to close the remaining header gaps.
- Fix the color contrast failure flagged by Lighthouse — ironic for a font tool and easy to resolve.
- Publish a short accessibility statement or WCAG conformance note to back up the 96/100 score.
- Consider a lightweight changelog or 'what's new' page to signal active development to returning users.

FontForge
Open-source font editor that also includes a font viewer, but requires installation and has a steeper learning curve.
Font Squirrel Webfont Generator
Web-based tool for converting and testing fonts, but focuses on webfont generation rather than detailed inspection.
Google Fonts
Offers a preview of Google-hosted fonts, but lacks deep inspection of local font files and advanced OpenType features.
