Short answer: HeicSave, HEIC.dev, and HEICcon all convert HEIC in the browser without uploading files to their servers. Pick HeicSave for no batch file cap, en/de/fr, and AVIF/WebP tools on one domain; HEIC.dev for more HEIC output formats and resize presets; HEICcon for built-in cloud import and parallel workers.

All three run conversion in the visitor's browser. None of them should receive your image bytes for processing when the tool is working as advertised—verify in Network tab if your threat model requires it (privacy guide).
When HeicSave is a better fit
- EU/German/French users who want tool pages and guides in their language.
- Large batches without a 50- or 500-file ceiling (still limited by device RAM).
- Developers who also need AVIF to JPG or WebP to PNG in one domain.
- Privacy audits — collapsible DevTools guide on tool pages; see privacy article.
When a competitor may win
- HEIC.dev — you need PDF/TIFF/AVIF output from HEIC in one UI, or heavy resize presets.
- HEICcon — you want Google Drive/Dropbox import buttons built-in.
- Cloud converters (FreeConvert, etc.) — only if you trust upload + delete policies (we don't recommend for sensitive photos).
What we don't claim
- Fastest on every device (parallelism depends on your CPU and browser).
- Perfect color match from P3 HEIC to sRGB JPG, see color guide.
- Live Photo video conversion, still images only.
