ConvertifyApp.net's answer:
Built out of frustration with existing converters that require signup or add watermarks. Wanted a fast, private, no-nonsense tool. Chose Rust + libvips for performance — the hardest part was getting HEIC support working by building libheif 1.21.2 from source.
ConvertifyApp.net's answer:
iPhone users who need to convert HEIC photos, web developers working with WebP and AVIF formats, and anyone who needs fast batch image conversion without installing softwar
ConvertifyApp.net's answer:
Convertify is completely free with no signup required and no watermarks. Most converters either require registration, add watermarks, or are slow. Convertify is built with Rust + libvips for maximum speed, supports 20+ formats including HEIC, and automatically deletes files after 6 hours for privacy.
ConvertifyApp.net's answer:
No signup, no watermarks, no limits on format combinations. Built with Rust + libvips — one of the fastest image processing libraries available. Supports HEIC conversion which most browser-based tools struggle with. Files are automatically deleted after 6 hours, so nothing is stored permanently. Batch convert up to 10 images at once with quality and resize controls.

This is a week late, but through the FreeMediaHeckYeah sub, I was able to discover sejda.com , which is basically an (almost) all-in-one PDF editor website. Was neat to realize I didn't even have to download any software whatsoever. Source: almost 4 years ago
Sejda.com - By far my most favorite experience but limits you to a # of docs per day. Source: about 4 years ago
Might try sejda.com. Also as u/jakethepeg111 suggests, Libreoffice Draw could be an option. Source: about 4 years ago

I run Convertify, a free image converter built on Rust and libvips. Last week I decided to stop guessing about format performance and actually measure it. I took 50 real images (26 PNGs, 24 iPhone HEIC photos), ran 17 conversions through... - Source: dev.to / 5 months ago
