Local HEIC workbench

Convert HEIC to JPG in your browser — free, private, no uploads.

Make an iPhone photo usable on the first screen. HEIC and HEIF are decoded into a verified JPG in this browser tab; PNG, PDF, WebP, batch controls, and manual transforms remain one click away.

No account or file upload endpoint
Output signature checked
Conservative memory budget

Private quick convert

HEIC to JPG, right here.

Local only

Drag a HEIC photo here

or paste a copied photo — only the first selected file enters this quick path

No HEIC handy? The demo is a 128 × 96 file generated from UnHEIC's own icon and bundled with this page.

Your photo bytes, filename, pixels, and extracted details are never sent as product telemetry. The decoder loads only after you choose, drop, paste, or request the bundled demo.

A result you can account for

01InspectRead a bounded header and estimate decoded work before conversion.
02Decode locallyHEIC decoding runs in browser Worker/WASM code where the library supports it.
03TransformApply output, quality, dimensions, background and orientation choices.
04VerifyCheck signature, MIME, extension and browser decodability before download.

Boundary: source EXIF, GPS, capture date and embedded ICC profiles are not preserved by the current HEIC decoder. The workbench says so before conversion.

Four intents, one retained session

Choose an output without choosing your files again.

The four HEIC routes have distinct instructions and limits, while an in-memory workbench keeps selected files available as you switch output.

Beyond HEIC

More image converters, same local path.

AVIF, WebP, PNG, JPG and BMP conversions run through the same bounded queue and the same signature, MIME, extension and browser-decode checks. Animated sources are refused rather than reduced to one arbitrary frame.

Truth before conversion

A file extension is only a claim.

The detector looks at bounded binary evidence, separates container from image brand, and says unknown when evidence is insufficient.

Verified policy

What survives the browser path?

These outcomes reflect the installed decoder and canvas/PDF encoders—not a preservation promise.

Signal	Output policy	Practical effect
EXIF / GPS / capture date	Stripped	Not copied into JPG, PNG or PDF image content.
ICC / wide gamut / HDR	Not preserved	Browser decode and canvas output may reduce color range.
Orientation	Preview + manual control	Decoder pixels are previewed; rotate/flip can be applied explicitly.
Transparency	Output-dependent	PNG can carry alpha; JPG uses the chosen background.
PDF text	Raster only	No OCR and no selectable text are created.
