- Mobile max file size: 20MB
Choose resolution, aspect ratio, DPI/PPI or file type under "Task". Check submission specs (such as 300 dpi or 1920×1080) and whether the extension matches the real format before uploading.
DPI appears only when stored in the file; many files, such as screenshots, have none.

Frequently Asked Questions (FAQ)
Does setting 300 DPI improve quality?
DPI is only print-size information; the pixel count is unchanged. Print quality depends on having enough pixels.
