HEIC to TIFF questions
How do I convert HEIC to TIFF?
Add one or more HEIC files, click Convert, then download each TIFF result or save the complete batch as a ZIP.
Are HEIC files uploaded to a server?
No. Conversion runs locally in the current browser tab, and the original files stay on your device.
Can I batch-convert HEIC to TIFF?
Yes. You can process up to 200 files, save results one by one, or download multiple results in one ZIP file.
What compression quality should I use?
For WebP and JPG, 75–89 is a useful range for most images. Higher values usually increase file size.
Will resizing stretch the image?
No. Width, height, and percentage resizing preserve the original aspect ratio.
What happens when output filenames are duplicated?
Duplicate names are kept unique by adding _(1), _(2), and so on.
