JPG to TIFF Converter
Convert JPG images to uncompressed TIFF files in batch. Ideal for prepress and archiving workflows, processed locally in your browser with complete privacy.
JPG, PNG, WebP, AVIF, GIF, BMP, ICO, TIFF, HEIC, SVG · up to 50 files
Tips
- Converting a JPG to TIFF encapsulates existing compression artifacts without restoring lost source detail.
- Uncompressed TIFF output significantly increases file size to satisfy strict commercial printing standards.
- Select multiple JPG files to convert an entire photo batch into TIFF containers simultaneously.
How to use it
- 1 Select or drag and drop your JPG files into the conversion area.
- 2 Review the queued images in the batch list.
- 3 Download the generated TIFF files individually or save all converted files at once.
What you should know
Commercial print shops, prepress technicians, and institutional archiving systems frequently require Tagged Image File Format (TIFF) rather than consumer-grade JPG files. While JPG relies on lossy discrete cosine transform compression that permanently discards chroma information to minimize file size, TIFF operates as a robust raster container that preserves uncompressed or losslessly compressed bitmap data. Prepress RIP software mandates TIFF to avoid re-compressing imagery during plate production. Although converting an existing JPG cannot restore data stripped by lossy encoding, saving it as TIFF halts further generational degradation during layout assembly.
This browser-based conversion engine decodes your JPG source files directly onto an HTML5 canvas element and re-encodes the raw pixel buffer into standard TIFF container files. Because the entire transformation occurs client-side within your browser tab, your source images are never transmitted over an external network. The generated TIFF uses full eight-bit RGB channels per pixel matching your input file. Note that converting a flat JPG file will not introduce multi-layer structures or 16-bit color channels, and camera EXIF metadata is stripped during raster serialization to ensure predictable layout software compatibility.
Frequently asked questions
Will converting a JPG to TIFF improve its image quality or resolution?
No, converting from JPG to TIFF cannot restore lost image detail or remove compression artifacts. It simply preserves the current pixel data in an uncompressed format to prevent further quality loss during editing or printing.
Why is the resulting TIFF file so much larger than the original JPG?
JPG files discard high-frequency data using lossy compression algorithms, whereas TIFF stores raw, uncompressed pixel arrays. A high-resolution photo may expand from a few megabytes to dozens of megabytes when converted.
Are my files uploaded to a remote server during conversion?
No, the entire conversion process runs locally in your browser using client-side canvas rendering. Your source JPGs and output TIFF files never leave your device.
