Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your iPhone HEIC photos into the high-capacity TIFF raster format for professional printing, archiving, and editing workflows.
HEIC is a space-saving raster image format utilized by Apple devices, typically compressed to save mobile storage. TIFF is an uncompressed or losslessly compressed raster image standard favored in publishing and professional photography. When converting HEIC to TIFF, you are moving a compressed file into a heavy format designed for maximum detail preservation.
Since HEIC is already compressed with potential data loss, converting it to TIFF preserves every remaining pixel and prevents any further degradation during editing, though it cannot recover details already lost in the original capture.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
