Many free converters:
- Upload your photos to their servers (privacy risk)
- Add watermarks
- Limit file size or number of conversions
- Inject malware
Solution: Use trusted tools like ours that process in your browser.
2. Converting to PNG Instead of JPG
PNG files are 3-5x larger than JPG for photos. Only use PNG if you need transparency.
Solution: Convert HEIC to JPG for photos, PNG only for graphics/logos.
3. Not Adjusting Quality Settings
Default quality settings may be too low (blurry) or too high (large files).
Solution: Use 85-90% quality for JPG. Our tool uses optimal settings automatically.
4. Deleting Original HEIC Files Immediately
If conversion fails or quality is poor, you'll need the originals.
Solution: Keep HEIC originals until you verify JPG quality.
5. Not Checking Metadata
Some converters strip EXIF data (date, location, camera settings).
Solution: Use converters that preserve metadata. Our tool maintains all EXIF data.
