Quality & file size · English guide
Choose the right quality for your JPEG.
A successful conversion gives you a usable image. A useful preview helps you decide whether that image is right for the job.
Open the HEIC to JPG converterJPEG quality is a tradeoff, including at 100%
JPEG is a lossy format: it compresses image information to make a broadly compatible photo file. This converter starts at 90% quality and lets you choose between 50% and 100%. Higher settings usually produce larger files with fewer visible compression artifacts; the exact result depends on the photo and browser.
A setting of 100% does not guarantee a bit-for-bit or visually identical copy of your HEIC original. It still exports JPEG from decoded 8-bit pixels. Start with the default, inspect fine edges, text, hair and smooth color transitions, and convert again at a higher setting if the preview needs it. The new conversion replaces the results in the tray; your source files remain unchanged.
When to choose JPG and when to choose PNG
Choose JPG for a photo that needs to work in an email, a website form or an everyday document. Choose PNG if you want to avoid an additional lossy JPEG step after decoding or preserve decoded transparency. JPG places transparency over white.
PNG stores the decoded pixels without JPEG compression, but it does not recover detail already missing from the original or undo color changes made during decoding. A PNG photo can be much larger than a JPG. Keep the original HEIC when you need the original capture data.
| Choice | Useful for | Tradeoff |
|---|---|---|
| JPG / JPEG | Photo sharing and compatible attachments | Lossy compression; alpha becomes white |
| PNG | Decoded pixel fidelity and transparency | Often a much larger download |
Why the JPG may be larger than the HEIC
HEIC and JPEG use different compression methods. Converting formats does not promise a smaller file, particularly at a high JPEG quality setting. The result tray shows the actual output size and dimensions so you can compare those numbers with a destination’s requirements.
The converter does not resize your photo; changing JPEG quality changes compression. If you need fewer pixels or a strict attachment size, first download the JPEG and use a separate image-resizing workflow. The Factory image resizer opens in a new tab. Opening another tool does not automatically transfer the photo: you choose the file again.
Resolution, orientation and color are different checks
For a supported image, this tool exports the decoded width and height rather than deliberately shrinking it. The decoder applies HEIF rotation and mirror information. The dimensions shown beside the result help you confirm what was exported.
Resolution alone is not a promise of original appearance. Browser canvas produces ordinary 8-bit output, and this converter does not promise to retain HDR, wide-gamut appearance or embedded color profiles. Inspect skin tones, bright highlights and saturated colors. For color-critical or archival work, keep the original and use a workflow that explicitly supports its color information.
What happens to dates, GPS and Live Photo motion?
This converter does not copy original date, camera or GPS metadata into the output. The filename is not proof that the original capture date survived. If a photo archive depends on that information, retain the HEIC alongside the converted copy.
Only the primary still photo is exported. Live Photo video, bursts, depth maps and additional images are outside this tool’s conversion path. JPG and PNG downloads here should be treated as shareable still-image copies.
A quick check before you download
- Check that the preview is upright and shows the expected still image.
- Read the dimensions and actual file size in the tray.
- Inspect detail and color; adjust quality or choose PNG if that better fits the task.
- Download and open the exported file in its intended destination.
- Retain the source HEIC when you need metadata, color fidelity or future editing options.
Each failed photo gets a specific message. Reduce the batch, remove an unsupported file or use a smaller original rather than repeatedly converting the same unsuitable input. Completed results remain available when you cancel a running batch.
Sources and scope
Apple device instructions were checked against Apple’s HEIF and HEVC support guidance on 13 October 2026. Converter behavior describes this tool’s current HEIC workbench, not every photo application. Device pickers and export options may vary.
The browser tool supports 20 photos · 20 MiB each · 80 MiB per batch, up to 24 megapixels and 8192 pixels per side. This guide does not promise support for every HEIF codec, color profile or device. Read the converter’s questions and limits.
