How JPEG compression works
JPEG divides an image into blocks and discards high-frequency detail the eye is least sensitive to. The quality setting controls how aggressive that discarding is. A well-tuned encoder can cut file size substantially before artifacts — blockiness, ringing around edges — become visible at normal viewing sizes.
Photographs with smooth gradients and natural textures compress best. Screenshots, line art, and text render poorly as JPEG at any setting; those belong in PNG or a modern format instead.
Why there is no lossless JPEG option
Standard JPEG is inherently lossy: every encode discards information, and re-saving at maximum quality still does not restore what earlier saves removed. Some tools advertise a lossless switch for JPEG anyway. Tinify does not — the option is simply absent for JPEG, because promising pixel-exact output from a lossy pipeline would be false.
If you need a pixel-exact result, convert the source to PNG, WebP, or AVIF and use lossless mode there. If you need a smaller photograph, Balanced or Best quality on JPEG is the honest path.
Picking between Balanced and Best quality
Balanced targets the point where further quality buys little visible improvement — appropriate for article images, listings, and thumbnails. Best quality keeps more fine grain and texture for hero photography and print-adjacent work. Try Balanced first and compare at 100% zoom; most images will not need the upgrade.
Targeting a specific file size
When a platform enforces an upload ceiling, use the target size field to aim for a byte budget in kilobytes. The encoder works toward that budget, and if the target is smaller than the image can honestly reach, you get a clear error rather than a silently broken file. Batches accept up to 50 JPEGs at once, and files are deleted after two hours.
Frequently asked questions
Can I compress a JPEG without any quality loss?
No. Standard JPEG re-encoding is always lossy, which is why Tinify never offers a lossless mode for JPEG. For pixel-exact output, use PNG, WebP, or AVIF with lossless mode.
How much smaller will my JPEG get?
It depends on how the file was originally saved. Lightly compressed exports often shrink a lot; already-optimized files may barely move. If compression would grow the file, Tinify returns the original and says so.
Is there a file size limit?
Each file may be up to 40 MB and 50 megapixels, with up to 50 files per batch in the free web tool.
