JPG to HEIC Converter
Convert JPEG files (released 1992, Lossy) to HEIC (Lossy (HEVC-based), typically ~50% smaller than equivalent JPEG). Runs in your browser — no upload, no signup.

Should you convert JPG to HEIC? It depends on where the file is headed. HEIC (Lossy (HEVC-based), typically ~50% smaller than equivalent JPEG) is the right call when you need iPhone photos, Apple ecosystem storage and sharing and your destination supports it — Safari only — convert for Chrome/Firefox/cross-platform. JPEG stays the better master when you need Photographs, hero images, anything where small file matters more than transparency. Output size depends on the resolution and content of your source image. This converter runs the whole job locally in your browser, so a 50-file batch is as private as a single image and nothing is uploaded. Below: a side-by-side of both formats, the real trade-offs, and the edge cases — transparency, animation, colour depth — that decide whether JPG → HEIC is a clean win.

Heads up before converting JPG → HEIC
What changes — and what your conversion will cost — based on how JPEG and HEIC differ.
Older clients may not render HEIC
HEIC support: Safari only — convert for Chrome/Firefox/cross-platform. Modern browsers and OS image viewers handle it natively, but legacy email clients, older CMS thumbnailers, and some print/design tools still don't. Confirm the downstream consumers in your pipeline accept HEIC before swapping at scale, or ship a JPEG fallback for the long tail.
Best practices for JPG → HEIC
Concrete settings to pick before you convert JPEG to HEIC.
- Always preview the HEIC output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- For photographic content, target a HEIC quality between 80 and 85 — that's the sweet spot where most encoders stop showing visible artifacts and the file size curve flattens.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to HEIC.
- For web HEIC delivery, encode in sRGB — wider colour spaces (Display P3, ProPhoto) render unpredictably across browsers and email clients.
When NOT to convert JPG → HEIC
Honest cases where this conversion is the wrong call — pick a different format or keep your JPEG source.
Skip if your audience uses legacy browsers
HEIC doesn't render on every old browser, email client, or built-in OS viewer. If your traffic includes IE11, legacy Outlook, or older Android WebViews, stay on JPEG (or a universal format like JPEG/PNG) — or ship HEIC alongside a fallback via the HTML <picture> element.
Skip if the file is bound for print
HEIC is a delivery-grade web format. Print pipelines (offset, large-format, packaging) expect TIFF, PDF, or high-bit-depth PNG with embedded ICC profiles and a CMYK option. Converting JPEG to HEIC for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
