For a sharper print, the image also needs enough pixel dimensions.
300 DPI at a given print size implies a minimum pixel count — for example, an 8×10in print at 300 DPI is 2400×3000px. If your image has fewer pixels than that, setting 300 DPI will not add the missing detail; it will simply mean the same pixels print smaller at true 300 DPI density, or larger with visible softness if you force the original print size.
300 DPI is the standard target for most professional printing — photo prints, magazines, and most print-on-demand products. Some large-format prints (posters, banners) use lower DPI since they're viewed from further away.
No. Setting 300 DPI only changes the metadata a printer reads — it does not add pixels. For a sharp print at a given size, the image also needs enough pixel dimensions to begin with; check that with the DPI Checker or Print Size Calculator first.
JPG and PNG files keep their format. WebP files are converted to PNG, since WebP has no widely supported editable DPI field — your pixels are copied over unchanged.
