Frequently Asked Questions
- Does converting JPG to TIFF improve image quality?
- No. JPEG compression permanently discards detail during encoding, and that data is gone forever. Converting to TIFF preserves exactly what remains and prevents further degradation in subsequent edits, but it cannot recover lost information.
- Why is my TIFF file so much larger than the JPG?
- Convertify writes a lossless Deflate-compressed TIFF. Lossless compression shrinks the file compared with raw uncompressed TIFF, but it cannot throw away detail the way JPG's lossy compression does, so the TIFF is still many times the size of the source JPG. The size scales with the image's pixel dimensions and how compressible its content is.
- Should I use TIFF or PNG after converting from JPG?
- TIFF for editing and archival workflows that expect it; PNG for web compatibility, design tools like Figma and Sketch, and general-purpose lossless storage. Both store the decoded pixels losslessly, and both use Deflate compression here, so file sizes are usually comparable. The choice is mostly about which format your workflow requires.
- Does JPG to TIFF conversion preserve EXIF metadata?
- No. Convertify strips metadata (EXIF, GPS, ICC profiles) from the output for privacy. Orientation and color profiles are applied during conversion, so images display correctly with accurate colors. Keep the original JPG if you need the metadata.
- Can I combine multiple JPGs into one multi-page TIFF?
- Yes. Enable the multi-page TIFF option and Convertify combines every uploaded JPG into a single multi-page TIFF, with each image stored as one page in upload order. By default, without that option, each JPG is converted to its own TIFF and returned in a ZIP.
- What TIFF compression does Convertify use?
- Lossless Deflate, also known as ZIP, with a horizontal predictor. There is not yet an option to choose a different scheme such as LZW or no compression, so every TIFF is Deflate-compressed. If you need a specific scheme, re-save in a desktop application after downloading.
- Can browsers display TIFF files?
- No. Chrome, Firefox, and Edge trigger a download prompt for TIFF files. Safari has partial native support. For web delivery, convert to WebP, AVIF, or JPG instead.
- Is JPG to TIFF conversion lossless?
- The conversion itself is lossless: no additional quality is lost beyond what the original JPG encoding already discarded. The decoded JPEG pixels are stored losslessly in the Deflate-compressed TIFF exactly as decoded.
- Can I resize the image during conversion?
- Yes. Use Convertify's <a href="/resize-image">image resizer</a> to set a custom width or crop to exact dimensions.

What actually happens when JPG becomes TIFF
JPEG is a lossy format. It discards high-frequency detail during encoding, and that data is permanently gone. Converting to TIFF does not restore those discarded pixels. What it does is decode the JPEG into full RGB values and store them with no further lossy compression. The result is a much larger file of the same image. The value of JPG to TIFF is not quality improvement, it is quality preservation: once the image sits in an lossless TIFF, it can be cropped, color-corrected, rotated, and re-saved repeatedly without accumulating the generation loss that every JPG re-save adds. TIFF freezes the image at its current quality.
When JPG to TIFF conversion makes sense
The main reasons to convert JPG to TIFF are re-editing and archival storage. A lossless TIFF can be opened, edited, and saved many times without the cumulative degradation that repeated JPG saving causes, which is why editing and preservation workflows favor TIFF over JPG. Libraries, museums, and archival systems often specify TIFF for long-term storage because it is a stable, widely documented format. One honest caveat about Convertify's output: it produces a standard RGB TIFF. It does not embed ICC color profiles, does not write specialized tags such as GeoTIFF coordinates, and does not produce CMYK or print-prepared files. If your workflow needs an embedded profile, CMYK, or specialized metadata, add those in a desktop editor after conversion. For web delivery this conversion makes no sense, since TIFF has zero browser support; for web-optimized output try JPG to WebP or JPG to AVIF instead.
File size: why your TIFF is much larger
Convertify writes the TIFF with lossless Deflate (ZIP) compression and a horizontal predictor, so the file is smaller than a fully uncompressed TIFF while staying pixel-for-pixel lossless. It will still be much larger than the source JPG, because lossless compression cannot match the ratios that JPG's lossy encoding achieves. As a rough guide, an 8-bit RGB image is on the order of width x height x 3 bytes before compression, and Deflate then trims that depending on content: flat graphics and text shrink a lot, busy photographic detail shrinks less. If you need an even smaller lossless file, PNG is often comparable since it also uses Deflate, but Convertify's TIFF is already compressed rather than raw.
Metadata and color profiles: what is carried over
Convertify strips metadata from the output for privacy. EXIF data (camera model, GPS, timestamps) is removed from the output file. Color profiles from the source are applied during conversion to maintain accurate colors, but the profile itself is not embedded in the output. Orientation is applied before stripping, so images display correctly.
Converting multiple JPGs: separate files or one multi-page TIFF
Upload several JPGs and Convertify converts each to its own TIFF by default, returning them together in a ZIP archive, one TIFF per source image. If you want a single document instead, enable the multi-page TIFF option: Convertify then combines every uploaded JPG into one multi-page TIFF file, with each image stored as a separate page in upload order. This is the format scanned contracts, fax archives, and multi-page document submissions expect. Choose separate files when each image is independent, or a single multi-page TIFF when the images belong together as one document.
TIFF compression: lossless Deflate by default
TIFF as a format supports several compression schemes, including LZW, ZIP/Deflate, CCITT Group 4 for bilevel scans, and uncompressed. Convertify writes lossless Deflate, also called ZIP, with a horizontal predictor, which is a strong general-purpose choice: it is widely readable and noticeably smaller than uncompressed TIFF. There is not yet a setting to pick a different scheme such as LZW or no compression, so every TIFF comes out Deflate-compressed. If your downstream system specifically requires LZW or uncompressed TIFF, re-save the file in a desktop application after downloading.
How Convertify converts JPG to TIFF
The Rust backend uses libvips, decoding the JPEG with libjpeg-turbo into full 8-bit-per-channel RGB, then writing the TIFF with lossless Deflate compression and a horizontal predictor. Metadata is stripped from the output for privacy. For multi-file uploads each JPG is written as its own separate TIFF by default; enable the multi-page TIFF option to combine them into one multi-page file. Processing streams server-side and files are deleted within 6 hours.
A short history of the TIFF format
TIFF, the Tagged Image File Format, was created by Stephen Carlsen at Aldus Corporation, with its first public release in 1986, developed with Microsoft to give early desktop-publishing scanners a common file format. Revision 4.0 in 1987 added uncompressed RGB, Revision 5.0 in 1988 added palette color and LZW, and TIFF 6.0, finalized in 1992, split the format into a Baseline part for maximum compatibility and an Extensions part for advanced features. Adobe acquired Aldus in 1994 and still administers the specification. That long, stable history is exactly why TIFF remains a standard choice for archival imaging, professional photography, and prepress, and why converting a JPG into TIFF is a reasonable step when a workflow specifically expects this format.
How to open the TIFF file you downloaded
One thing that surprises many people is that web browsers do not display TIFF files natively, so double-clicking a .tif rarely opens it in a browser tab. On Windows, open it with the Photos app or the legacy Windows Photo Viewer. On macOS, Preview opens TIFF files and can also re-export them. Cross-platform viewers such as IrfanView, XnView, and GIMP open TIFF as well, and most professional imaging and document software reads it directly. The file Convertify produces is a standard TIFF, single-image or multi-page depending on your choice, and any of these tools will open it without special handling.
