Frequently Asked Questions
More on quality loss: conversion quality guides · compression guides
Is Base64 the same as converting formats?
No. Base64 wraps the same binary as text (~33% larger). Use converters when you need JPG→PNG.
Does compressing or converting images reduce quality?
Lossy compression can. Use higher quality settings when fidelity matters, and keep an original master. Lossless workflows preserve pixels.
Can you recover quality after compressing?
Not from the compressed file alone. Keep the original upload/export and recompress from that master if you need a better result.
What is generational loss?
Quality damage from repeatedly re-encoding lossy images. Avoid save→compress→save loops; work from a master.
