Why use Aback Images for heic to jpg
Where the JPG goes next
JPG opens in every operating system, browser, phone, photo kiosk and image editor.
JPG next to HEIC
Both formats are lossy, so the size mostly follows the quality setting; at the default the JPG usually lands in the same range as the HEIC.
A second lossy pass
HEIC is lossy already, since it stores lossy HEVC (H.265) intra coding, on iPhones as a grid of 512×512 tiles, so keep the quality at or above the default to avoid stacking a new layer of artefacts on the old one.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
HEIC vs JPG
What changes from HEIC to JPG
Encoding: the HEIC uses lossy HEVC (H.265) intra coding, on iPhones as a grid of 512×512 tiles; JPG uses lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution, and the download is a standard JPEG at the quality you choose.
Bit depth: 8 or 10 bits per channel in the HEIC; JPG allows 8 bits per channel, and the JPG written here has 8 bits per channel. 10-bit HEIC photos are reduced to 8 bits per channel.
Colour: YCbCr, usually tagged Display P3 on iPhones in the HEIC; JPG supports YCbCr shown as RGB, greyscale, or CMYK from print software, written here as 8-bit sRGB.
Transparency: the HEIC stores it as an auxiliary image item, rarely used by cameras; the JPG has none, so transparent areas are filled with the colour you choose.
Other images: the HEIC can hold a thumbnail, depth map, HDR gain map and burst shots as extra items; only the main image is converted.
Metadata: the HEIC can carry EXIF, XMP and an ICC profile, stored as items; JPG can carry EXIF (camera, date, GPS), XMP, IPTC and an ICC profile in APP segments, but nothing is copied across.
About HEIC
HEIC is the default photo format on iPhones and many Android phones. It is about half the size of JPEG, but Windows, many websites and older software cannot open it without converting.
A HEIC is a HEIF file (ISO base media boxes with the brand 'heic'). iPhone photos store the picture as a grid of 512×512 HEVC tiles that the decoder stitches together, with the thumbnail, depth map and HDR gain map as further items.
HEIC files usually come from iPhones and iPads since iOS 11, and many recent Android phones.
About JPG
JPEG is the universal photo format. It compresses by discarding fine detail the eye is least sensitive to, which makes photos small but blurs sharp edges and text if pushed too far.
A JPEG starts with the bytes FF D8 and is a run of marker segments: APP1 carries EXIF and often a thumbnail, APP2 an ICC profile, DQT the quantization tables that decide the quality, and SOS the compressed scan, which ends at FF D9.
When converting HEIC to JPG makes sense
JPG is the better choice for photographs that need to open anywhere, while HEIC suits storing photos on Apple devices.
JPG strengths: Opens everywhere: every browser, phone, camera, printer and app; Small files for photographs; Adjustable quality from tiny to near-lossless. Drawbacks to weigh: No transparency; Lossy: every re-save loses a little more; Blocky artifacts around text, logos and sharp lines.
Limitations
- HEIC is already lossy, so a second lossy pass should stay at a high quality setting.
- iPhone photos are usually Display P3; colours are mapped to sRGB, so very saturated reds and greens can look slightly less vivid.
- JPG has no transparency and no animation; it is the safest choice when a file must open on any device or upload form.
- Each time a JPG is edited and saved again it loses a little more detail, so keep your original for further editing.

Frequently asked questions
Does converting HEIC to JPG lose quality?
JPG is lossy, so detail the eye barely notices is discarded to save space. The HEIC was lossy already, so keep the quality high to avoid stacking artefacts. 10-bit HEIC photos are reduced to 8 bits per channel. Not carried over: any a thumbnail.
What happens to transparency when converting HEIC to JPG?
HEIC stores transparency as an auxiliary image item, rarely used by cameras. JPG has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
Why can't I open HEIC photos on Windows or websites?
HEIC uses the HEVC codec, which is patent-encumbered and not built into most browsers, Windows apps and upload forms. Converting makes the photo open where HEIC does not, and the HEIC is decoded inside your browser to do it.
What quality should I choose for JPG?
85 to 92 looks identical to the original for most photos. 70 to 80 saves a lot more with little visible change. Below 60, blocking appears around edges and in skies.
Which apps open JPG files?
Every operating system, browser, phone, photo kiosk and image editor.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
