Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does converting WOFF to WOFF2 reduce quality?
Often no for lossless or remux-style paths. Quality drops when you re-encode with lossy settings, downscale, or flatten features like transparency.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
Do you upload my font?
No. Font conversion runs in your browser with local JS/WebAssembly. Files are not uploaded to Format Convertly.
Are glyph outlines changed?
No for container conversions (TTF/OTF ↔ WOFF/WOFF2). Outlines stay the same; only the wrapper/compression changes. CFF→TrueType redraw is not supported in-browser.
