Why does my HEIC not open on Windows or the web?

HEIC uses HEVC intra-frame coding, which is patent-encumbered. Only Apple platforms ship the decoder by default; Windows requires a paid codec pack for many users, most Linux distributions do not ship one at all, and browser support for HEIC itself sits at roughly 20% globally. Converting to JPEG sidesteps the decoder problem entirely: the output plays in essentially every browser, CMS, and image viewer.

Will I lose quality converting HEIC to JPEG?

For typical smartphone photography at the default quality target, the JPEG output is visually indistinguishable from the source HEIC at normal viewing distance. Where you may notice a difference is HDR highlights (if the JPEG target is SDR-only, the highlight range collapses) and wide-gamut saturation (if the target is sRGB, Display P3 colours are re-mapped). For hero images and social posts, those differences are invisible.

What happens to my upload?

Your upload is only held while we process it (usually a few seconds) and is deleted the moment we send the result back. Nothing is saved on our servers, nothing is indexed, and nothing is used for model training. No account is required, so there is nothing tying the upload to your identity in the first place.

The free tier is one image per request. The paid Optimizer tier batches up to 50 images per job and ships a ZIP of outputs with consistent quality settings across the whole batch. Batch is useful when you have a catalogue to re-encode or a backlog of iPhone photos to normalise for the web.

Does my HEIC contain GPS coordinates?

Almost certainly yes. iPhone photos embed your latitude and longitude in the EXIF block by default, along with camera model, lens, and capture time. The conversion preserves that metadata into the JPEG, so if you are publishing the output publicly, run the EXIF strip tool first. For personal archive use (iCloud, Photos library), the EXIF is what makes the photo searchable and should be kept.

When should I NOT convert HEIC to JPEG?

Do not convert when the destination is another Apple device (keep the HEIC: it is smaller and opens natively). Do not convert when you are archiving camera originals: the HEIC is the authoritative source and any transcode is a generation loss. Do not convert when wide-gamut colour or HDR matters and the target cannot preserve it: pick AVIF instead, which natively preserves Display P3 and HDR.

Convert HEIC to JPEG. iPhone and iPad cameras save photos as High Efficiency Image Container by default, and HEIC is not a web format: most browsers refuse to display it, most CMS importers reject it, and Windows users see a "file type not supported" error. This tool re-encodes your HEIC as a JPEG that plays everywhere, with no resizing and nothing kept on our side.

JPEG (JPEG) is a delivery-friendly target standardised in 1992 and supported in roughly 100%% of 2026 browsers. It is the right landing spot when the use case is publishing on the web, sending over email, or handing the file to a non-Apple collaborator. At visual parity with the source HEIC, the output is about 118% of the byte cost, which is the right balance of quality and compatibility.

HEIC (High Efficiency Image Container) is the Apple-platform camera default. It uses HEVC intra-frame coding to pack high-quality photos into small files, preserves wide-gamut colour, and supports HDR. All of that is great for the iCloud round-trip and for on-device viewing, but terrible for web delivery: browser support for HEIC itself stalled at about 20% globally and has not moved in years.

The trade-off is metadata fidelity. HEIC often carries a Display P3 colour profile and HDR metadata; converting to JPEG may collapse those to sRGB depending on the target format chosen. For Instagram, web hero images, and blog covers that is the right call. For a gallery site that deliberately ships wide gamut, convert to AVIF instead, which preserves Display P3 and HDR natively.

When NOT to convert HEIC to JPEG: when the destination is an Apple-platform viewer (keep the HEIC; iOS Photos, macOS Preview, and Apple Mail open it natively and save space). When you are archiving camera originals (keep the HEIC as the master). When the wide-gamut or HDR metadata matters and the target format cannot preserve it: pick a modern codec such as AVIF instead.

Your HEIC upload is held only while we transcode it. The resulting JPEG comes back on a one-time download link and is deleted the moment you fetch it. Camera EXIF (including GPS coordinates, if present) is preserved by default: run the EXIF strip tool before publishing a camera HEIC publicly, because iPhone photos embed your location in the image itself.

HEIC to JPEG at a glance

Tallene og afvejningerne du har brug for, før du beslutter dig.

Where HEIC comes from
iPhone and iPad cameras save photos as HEIC by default since iOS 11. Apple-platform viewers open it natively; almost nothing else does.
Browser support cliff
Browser support for HEIC itself sits at roughly 20% globally and has not moved in years. JPEG reaches about 100%%.
Size at visual parity
At the default quality, JPEG lands at roughly 118% of HEIC byte cost on typical smartphone photography.
GPS metadata warning
iPhone photos embed GPS coordinates in EXIF. The conversion preserves that metadata into the JPEG; strip it before publishing publicly.
Colour fidelity
HEIC often carries Display P3 and HDR metadata. The JPEG output preserves those profiles only if the target format supports them.
When to keep HEIC
Keep the HEIC when the destination is another Apple device or the iCloud library: it is smaller and opens natively.
Year standardised
HEIC was standardised in 2015 and JPEG in 1992. The gap drives both the quality and the compatibility difference.

Arbejdsgang

Sådan virker det

Tre trin, normalt færdige inden for fem sekunder.

1
Upload an iPhone HEIC
Drop a HEIC up to 25 MB, or paste from the Mac clipboard. AirDrop the file to your computer first if iOS refuses to expose the raw file.
2
We transcode it to JPEG
We decode the HEVC payload inside your HEIC and re-encode it as JPEG at a default quality that matches the source visually. Camera EXIF is preserved by default.
3
Download your JPEG
Your JPEG comes back on a one-time download link that plays on Windows, Linux, the open web, and every email client. The original HEIC is deleted the moment you fetch.
