Change Image DPI
Change the DPI value recorded in an image without touching a single pixel. Print shops and publishers frequently reject images for being "72 DPI" when the pixel dimensions are perfectly adequate; this fixes the metadata they are reading. It is free, needs no account, and adds no watermark to your result.

What people use it for.
What happens to your file.
For JPEG and PNG, the resolution fields in the file (the JFIF density and EXIF resolution, or the PNG pHYs chunk) are rewritten in place to your chosen value, so the compressed image data, the colour profile and the dimensions are left exactly as they were. Other formats come back as PNG carrying the new value.
Where it stops: DPI is only a printing instruction. Raising it does not add detail. If an image is genuinely too few pixels for the print size, use the upscaler instead.
Everything you need, without a paywall.
Common questions.
Does raising DPI improve quality?
No, and it is important to understand why. DPI only tells a printer how large to render the existing pixels. A 500-pixel image labelled 300 DPI still has 500 pixels.
Why did my printer reject a 72 DPI file?
Many workflows check the DPI field rather than the pixel dimensions. If your pixel size is adequate, changing the field is the correct fix.
What if my image really is too small?
Then you need more pixels. Use the Image Upscaler first, then set the DPI.
You might also need.
Upscale images by 2x or 4x with the bundled local Real-ESRGAN neural super-resolution model for sharper detail and artifact reduction, free with no credits.
Inspect image dimensions, format, EXIF fields, camera data, orientation, DPI and embedded metadata as JSON.
Resize images by pixels or percentage. Maintain aspect ratio and use presets for popular websites and social platforms.
Strip EXIF, GPS and common image metadata while retaining image dimensions and visible content. Choose PNG, JPEG or WebP output.
