Does switching to 300 DPI improve quality?

No. Without changing the pixels, going from 72 to 300 DPI makes the print smaller and finer, not more detailed. To print larger at 300 DPI you need more pixels: the print size option works them out, but enlarging does not create detail.

Which resolution should I choose?

300 DPI for a careful print, photo or brochure; 150 DPI for a poster seen from afar or an everyday document; 72 DPI when the image is only for screens, which ignore this value.

Is my file recompressed?

For JPG, PNG and WebP, no: the resolution is written in the file header, and the pixels and other metadata stay identical. A HEIC, whose resolution print software does not read, becomes a JPG, or a PNG if it is transparent. A WebP carries its resolution in its EXIF data, which some software ignores.

Can I process several images at once?

Yes: up to three per operation, all with the same settings. You get a ZIP archive in which each keeps its name. The Pro plan processes fifty at a time.

Are my images sent to a server?

No. Your image is not transmitted to us: we know neither its name nor its contents. There is nothing to delete afterwards.

How it works

Three steps, nothing more.

Step 01
Drop one or more JPG, PNG, WebP or HEIC images.
Step 02
Choose 72, 150, 300 DPI or a custom value, or enter the print size you want in centimetres or inches.
Step 03
Download the print-ready image, or the archive of all of them.

What sets it apart

Built for the result.

The pixels stay untouched

Changing the resolution only edits a label in the file: the photo is neither recompressed nor resized, only its size on paper changes.

02

An exact print size

Enter 10 cm or 4 inches wide: the image gets the number of pixels the chosen resolution requires, and you see the size before and after.

Accepted formats

Another question? The contact address is at the bottom of the page.

Pixels are the content of the image; DPI (dots per inch) only says how many of those pixels fit in an inch once printed. A photo 3,000 pixels wide prints 10 inches wide at 300 DPI and 20 inches at 150 DPI: same image, same sharpness on screen, only the size on paper changes.
