How JPG to HEIC conversion works
JPG is everywhere because it’s compatible and compact. HEIC (HEIF) is popular on iPhone because it stores photos efficiently while keeping good visual quality. This converter redraws each JPG image onto a canvas and then encodes it as HEIC, entirely in your browser.
Want to make HEIC usable anywhere by reversing conversion? Use our HEIC to JPG Converter. In case you need a web-friendly modern format, try this JPG to WEBP Converter.
When to use this tool
Use the JPG to HEIC tool whenever you:
- Want smaller photo files for iPhone-style storage.
- Prefer keeping a consistent HEIC photo library in Apple Photos.
- Have many JPG exports and want a more iOS-native format.
- Need batch conversion without uploading images to any server.
Step-by-step: from JPG to iPhone-style HEIC
Converting your photos follows a short, repeatable routine:
- Add your JPG photos. Drag files into the drop area or click to choose them from your device.
- Adjust quality. Use the slider to balance HEIC file size and detail.
- Optionally keep basic metadata. Where supported, the tool respects key information such as creation date and orientation.
- Convert. Start the conversion and wait for each photo to be processed locally in your browser.
- Save your HEICs. Save files one by one or use the “Save all HEICs” button once everything is ready.
Privacy, limits and how this tool treats your images
FileYoga follows a simple rule: your files stay with you. This converter runs locally in your browser — nothing is uploaded or stored on a server.
Local-only conversion
Photos are processed in your browser. We do not upload, scan or store your files on FileYoga servers.
No hidden copies
When you clear the list or close the tab, the tool stops using your files and does not save copies on a server.
No artificial limits
No paywalls or quotas. The only limits come from your device’s memory and your browser.
No account required
Use the converter without signing up. Open the page, convert your photos, and leave when you are done.
Limits to know about:
- Compatibility: HEIC is great on iPhone/iPad/macOS, but some Windows apps and older software may not open HEIC files.
- Device memory: Large photos and big batches can slow or crash the tab. Convert in smaller groups if needed.
- Metadata: Some browsers can’t preserve all EXIF metadata through a canvas export. Keep the original JPG if metadata matters.
- Quality reality: Converting can’t restore detail lost to heavy JPG compression — it’s mainly a format/storage change.
Quality and file size for HEIC
HEIC is designed to store photo-like images efficiently. The slider in this tool lets you choose how much detail to keep versus how small you want the file to be. Higher values keep more detail but create larger files.
Helpful for large batches, quick sharing and general photo storage where smaller files matter most.
A strong everyday setting. Photos look clean in Apple Photos and keep good detail without becoming huge.
Best for archiving important photos or keeping extra detail for cropping later. Files will be larger.
If you are unsure where to start, use the default setting and adjust only if files feel too large for sharing or you want to keep more fine detail.
What happens to photo information
Digital photos often carry extra information such as the date, time, device model and orientation. This tool lets you choose whether to:
- Keep basic metadata: helpful for sorting photos by date or keeping them upright automatically.
- Remove metadata: useful when sharing images publicly or when you want leaner, more anonymous files.
If you are importing photos into Apple Photos, keeping metadata is usually convenient. For public websites and broad sharing, you may prefer to turn it off.
Tips for best results
- HEIC is ideal for photo-like images. If you are converting logos, icons or graphics that need transparency, use a PNG workflow instead.
- If you want maximum compatibility with older apps or Windows workflows, keep the original JPG files too. HEIC is great for iPhone-style storage, but not every app handles it perfectly.
- If your JPG is already heavily compressed, converting to HEIC cannot restore lost detail. Treat conversion as a storage and workflow change, not a “quality upgrade”.
- Because everything runs in your browser, conversion speed depends on your device and the size and number of JPG files you add at once.
Troubleshooting
- My HEIC won’t open on Windows. Some apps don’t support HEIC. Convert back using HEIC to JPG for compatibility.
- My HEIC is bigger than the original JPG. Some JPGs are already optimized. Lower the quality slider and convert again, or keep JPG for that image.
- Photos look softer than expected. Try a higher quality setting. If the input JPG was heavily compressed, lost detail can’t be recovered.
- Conversion is slow or fails. Large images and big batches can hit memory limits. Convert fewer files at once and close other heavy tabs.
- Metadata didn’t carry over. Some browsers drop metadata during export. Keep the original JPG if metadata is important.
Frequently asked questions
HEIC is widely supported on iPhone, iPad, and modern macOS. Some older Windows apps and web tools may not open HEIC without an extra codec or converter. If you need maximum compatibility, keep your original JPGs as a backup.
Some JPGs are already heavily optimized. If the original is very small or already compressed aggressively, HEIC may end up similar in size (or occasionally larger). HEIC tends to shine most on higher-resolution photos or images with lots of detail.
The slider is a “quality intent” control: higher values aim to keep more detail, while lower values prioritize smaller files. Depending on the encoder build available in your browser, the effect can be subtle on some images. If size matters most, try lowering the slider and converting again.
No. The tool keeps your image dimensions the same. It only changes the file format from JPG/JPEG to HEIC.
Most browsers can’t reliably carry full EXIF metadata through a canvas-based conversion (camera model, GPS, etc.). If metadata is important, keep the original JPG as your “master.” The HEIC output is best treated as a clean photo copy.
There’s no artificial limit. The practical limit is your device memory and your browser. If the tab slows down or crashes, convert in smaller batches (for example 10–30 photos at a time).
No. Files are processed locally in your browser. Your images are never uploaded to FileYoga servers. The only downloads are the HEIC files you choose to save.
For many photos, JPG already looks good. HEIC is mainly a storage/workflow format: it may reduce file size, but it won’t “upgrade” a heavily compressed JPG. The biggest wins usually come from higher-resolution photos or less optimized inputs.
