- Conversion starts right away. Download each TIFF file, or click Download all to get them as one ZIP.
HEIC vs TIFF
| HEIC | TIFF | |
|---|---|---|
| Compression | Lossy | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | No | No |
| Colors | 8–10 bits per channel | Up to 16 or 32 bits per channel, multiple pages |
| File size (photos) | Very small (about half of JPG) | Very large |
| Opens on | iPhone, iPad and Mac out of the box; Windows needs extra Microsoft Store extensions; most websites and Android apps do not accept it | Photoshop, scanners, print and publishing software; only Safari displays it in a browser |
| Best for | Storing photos on Apple devices without filling up the storage | Scans, printing, publishing and archiving at maximum quality |
About HEIC and TIFF
What is HEIC?
HEIC is the format iPhones and iPads use for photos by default. It compresses images with HEVC (H.265) video technology, so photos take about half the space of a JPG at the same quality. The catch: Windows PCs, many websites, online forms and Android apps cannot open HEIC files, which is why people convert them to JPG.
- About half the size of JPG
- Keeps 10-bit color and depth/Live Photo data
- Default on every recent iPhone
- Not supported on most Windows PCs without paid extensions
- Rejected by many websites and upload forms
- Only Safari can display it in a browser
What is TIFF?
TIFF is the workhorse of scanning, printing and professional photography. It can hold uncompressed or losslessly compressed pixels at high bit depths, several pages in one file and lots of metadata. That flexibility makes files big, and browsers (except Safari) cannot display TIFF at all.
- Lossless and print-ready
- High bit depth and multiple pages
- Industry standard for scanners and printers
- Very large files
- Cannot be shown on most websites
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Will converting HEIC to TIFF reduce quality?
TIFF uses lossy compression, but at the default quality of 90% the difference is practically invisible, even though the HEIC was already compressed. Move the quality slider down for smaller files, or up to 100% for the best possible result.
Is transparency kept?
Yes. Transparent and semi-transparent areas are kept as they are.
Will the TIFF file be smaller than the HEIC?
Usually not. TIFF files are typically about the same size or larger than HEIC. If you need a small file, try WebP or compress the image.
Why are my iPhone photos saved as HEIC?
Since iOS 11 (2017), iPhones and iPads save photos as HEIC because it needs about half the storage of JPG at the same quality. The downside is compatibility: Windows PCs, Android phones and many websites cannot open HEIC files.
How do I make my iPhone take JPG photos instead?
Open Settings → Camera → Formats and choose Most Compatible. New photos will be saved as JPG (and videos as H.264). Photos you already took stay HEIC — convert them here.
Can I convert several HEIC images at once?
Yes. The free plan handles 10 images at a time, and you can download everything as a single ZIP. Pro removes the batch limit, converts files in parallel and supports files up to 4 GB.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
