Does adjusting DPI damage JPEG quality?

No. Deliteful writes only the DPI metadata tag and does not decompress or recompress the JPEG. There is zero generation loss — the file is bit-for-bit identical aside from the metadata change.

My print lab requires 300 DPI. Will this tool make my photos print at higher quality?

It ensures the lab software interprets your existing pixels at the correct print size. If your photo already has enough pixels for the intended print dimensions, correcting the DPI tag will get rid of upscale warnings. It does not add pixels or increase sharpness.

Can I batch-adjust DPI for an entire shoot?

Yes — upload multiple images in one session and apply the same DPI value to all of them simultaneously.

Set the Right DPI for Photo Lab Submissions Without Resampling

Print labs reject or poorly scale photos when DPI metadata doesn't match submission requirements — and the fix shouldn't mean re-exporting from Lightroom or Capture One. Deliteful corrects DPI metadata on your exported JPEGs and PNGs in seconds, preserving every pixel of your original export.

Most print labs specify 300 DPI at final print size, but camera exports and culling software often tag files at 72 or 96 DPI by default. When a lab's RIP software reads 72 DPI on a 6000×4000 px file, it calculates an 83-inch wide print — triggering upscale warnings or automatic rescaling that degrades edge sharpness. The fix is not to re-export with a new setting; it's to correct the existing metadata tag so the lab software maps your pixel grid correctly to the intended physical dimensions.

Deliteful's DPI adjustment is a pure metadata write — no decompression, no recompression, no generation loss on your JPEGs. You set the target DPI (72 to 2400), upload the files, and download corrected copies. For photographers delivering to multiple labs with different requirements, this removes a friction point that otherwise means round-tripping back into a raw processor.

How it works

1
Export images from your raw processor
Export at your usual settings from Lightroom, Capture One, or similar — DPI setting in the export dialog does not matter.
2
Upload to Deliteful
Drop your JPEG, PNG, or WebP files into the tool.
3
Enter the lab's required DPI
Type the value specified by your print lab — typically 300 DPI for standard prints.
4
Download corrected files
Retrieve your files with updated DPI metadata, pixels and quality untouched.
