How HEIC to WEBP conversion works
HEIC is the default photo format on many iPhones because it stores high-quality images efficiently. On the web, WEBP is a popular choice because it delivers smaller files while keeping images looking sharp. This converter decodes each HEIC image locally and exports it as WEBP in your browser.
Need a different output? Try our HEIC to JPG Converter for maximum compatibility, or HEIC to PNG Converter for a lossless workflow. If you want to go the other direction, use this WEBP to HEIC Converter.
When to use this tool
Use the HEIC to WEBP tool whenever you:
- Want to publish iPhone photos on a website with faster loading.
- Need smaller image files for product pages, blogs, documentation or dashboards.
- Send lots of images through tools that support WEBP and want to reduce bandwidth.
- Prefer a modern web format over JPG for a better size-to-quality balance.
Step-by-step: from HEIC to ready WEBP
Converting your images follows a short, repeatable routine:
- Add your HEIC photos. Drag files into the drop area or click to choose them from your device.
- Adjust quality. Use the slider to balance WEBP file size and detail.
- Optionally keep basic metadata. Where supported, the tool respects key information such as date and orientation.
- Convert. Start the conversion and wait for each file to be processed locally in your browser.
- Save your WEBPs. Save files one by one or use the “Save all WEBPs” button once everything is ready.
Privacy, limits and how this tool treats your images
FileYoga is built around a simple rule: your files stay with you. This HEIC to WEBP converter follows that rule closely.
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:
- Decoder + browser support: HEIC conversion requires the decoder script to load and run in your browser environment.
- Device memory: Large photos and big batches can slow down or crash the tab. Convert smaller batches if needed.
- Metadata: Some HEIC metadata (EXIF details) may not survive a decode → canvas → export workflow. Keep the original HEIC if you need full metadata.
- Wide-gamut color: Some HEIC photos use wide color profiles. WEBP output may look slightly different depending on browser color management.
Quality and file size for WEBP
WEBP is designed for efficient delivery. 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 publishing and pages where file size matters more than pixel-level detail.
A strong everyday setting. Images stay clean for most sites while keeping sizes friendly.
Best when you want extra detail for zoom, cropping or hero images. Files will be larger.
If you are unsure where to start, use the default setting and adjust only if files feel too large for your site 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 by date and keeping images upright.
- Remove metadata: useful when publishing images publicly or when you want leaner files.
In many browsers, decoding HEIC and re-encoding to WEBP can drop some metadata. If metadata is critical, keep the original HEIC as your master copy.
Tips for best results
- Keep the original HEIC as your master if you may re-edit later. WEBP is ideal for delivery, not archival.
- Use lower quality for thumbnails and galleries, and higher quality for hero images and product close-ups.
- If a platform does not accept WEBP, convert to JPG instead for broad compatibility.
- For huge batches, convert 10–30 photos at a time to reduce memory spikes.
Troubleshooting
- The page says my HEIC is unsupported. Try another modern browser and make sure the decoder script is not blocked by an extension or content policy.
- Conversion is slow or the tab crashes. Reduce batch size, close heavy tabs, and try again. Large HEIC photos can be memory intensive.
- Colors look different after conversion. Some HEIC photos use wide-gamut profiles. Try increasing quality, or test output in your target browser/site pipeline.
- My WEBP is larger than expected. Lower the quality slider and reconvert, especially for simple photos that were already efficiently stored.
- Metadata didn’t carry over. Some metadata can’t be preserved through a canvas export. Keep the original HEIC if you need full EXIF.
Frequently asked questions
No. Conversion happens locally in your browser. Your HEIC files never leave your device, and the WEBP files are generated on your side.
HEIC is common on iPhone for efficient photo storage. WEBP is popular on websites because it delivers smaller images that load quickly in modern browsers.
HEIC decoding requires the in-page decoder and a compatible browser environment. If the decoder script is blocked by an extension or policy, the file may fail to load. Try another browser and ensure site scripts are allowed to run.
Not always. A decode → canvas → export workflow may drop some EXIF fields (camera model, GPS, etc.). If metadata matters, keep the original HEIC as your master.
HEIC can be extremely efficient for certain photos. If the WEBP output is larger, lower the quality slider and convert again. The “best” format depends on the image content and target use (web delivery vs storage).
No. It keeps the original pixel dimensions and only changes the file format from HEIC/HEIF to WEBP.
Start with the default “High” setting. For thumbnails and galleries, you can lower quality to reduce size. For hero images and product close-ups, increase quality if you see artifacts.
There’s no artificial limit. The practical limit is your device memory and browser. If the tab slows down, convert in smaller batches (often 10–30 photos at a time).
