TransformaHow to Convert TIFF to JPG on iPhone
TIFF is a lossless image format favored in photography, printing, and scanning, but the files are enormous — a single high-resolution TIFF can be 30-100MB or more. Converting to JPG compresses the image to a fraction of that size, making it practical to email, upload, or share. Transforma converts TIFF to JPG entirely on your iPhone using CoreImage, with adjustable quality settings so you control the size-quality tradeoff.
Quick Answer
Open your TIFF file in Transforma, tap JPG, set your quality level (92% recommended for photos), and convert. File size typically drops by 90% or more, and the visual difference is imperceptible at high quality settings.
Why You Might Need This
- TIFF files are often 30-100MB+, making them impractical to email, message, or upload to most platforms that have file size limits.
- Scanned documents saved as TIFF need to be converted to JPG for emailing, web upload, or inclusion in presentations.
- Professional photography workflows output TIFF for editing, but final delivery to clients is almost always in JPG format.
- Social media platforms and websites don't accept TIFF uploads — JPG is the universal web image format.
- Batch converting a folder of TIFF scans to JPG can free up gigabytes of storage on your iPhone.
Step by Step
Open Transforma and select your TIFF file
Launch Transforma and browse to your TIFF file. You can import from the Files app, iCloud Drive, email attachments, or any connected storage provider.
Choose JPG as the output format
Tap JPG from the available output formats. Transforma uses CoreImage to handle the conversion, supporting all standard TIFF variants including those from scanners and professional cameras.
Adjust the quality setting
Set the JPG quality between 80-95%. A setting of 92% produces visually identical results for photographs while achieving maximum file size reduction. Lower values produce smaller files with slightly more compression artifacts.
Save the converted JPG
Save to your Camera Roll, Files app, or share directly via email, Messages, or AirDrop. The JPG file is ready to use anywhere that accepts standard image formats.
Tips for Best Results
- TIFF to JPG typically reduces file size by 90% or more — a 50MB TIFF scan becomes a 3-5MB JPG at high quality.
- Quality setting of 92% is visually identical to the original for photographs and produces the best balance of size and fidelity.
- Keep your original TIFF files for archival and printing purposes — TIFF preserves every pixel, which matters for professional reproduction.
- This conversion is particularly useful for scanned documents that need to be emailed, as most email services limit attachments to 25MB.
- Use Transforma's batch conversion to process multiple TIFF files simultaneously, saving time when converting an entire scan folder.
Frequently Asked Questions
Why are TIFF files so large?
TIFF is a lossless format that stores every pixel without any compression (or uses lossless LZW compression). This preserves perfect image quality, which is essential for printing and professional editing, but results in files that are 10-50x larger than the equivalent JPG.
Does converting to JPG lose quality?
Technically yes, since JPG uses lossy compression, but at quality settings of 90% or higher the difference is imperceptible to the human eye. For photographs, 92% quality produces a file that looks identical to the TIFF original while being dramatically smaller.
When should I keep the TIFF format?
Keep TIFF for archival storage, professional printing, and any workflow where you'll be making further edits. Each time you save a JPG, a small amount of quality is lost through recompression. TIFF avoids this problem entirely, making it the right choice for source files.
Can Transforma handle multi-page TIFF files?
Transforma handles standard TIFF files including those produced by scanners and professional cameras. For multi-page TIFF documents, each page is processed as part of the conversion to produce your JPG output.
