Image DPI Converter
Estimate print size from pixels and target DPI, then export a browser-side image copy with practical print-planning notes.

JPG, PNG, WebP, SVG, GIF, and browser-readable images.
Mobile processing guidance
On mobile, start with one browser-readable image under 10MB before trying larger files.
25MB recommended limit.; keep very large images under browser memory limits.
Canvas-based image operations can fail when pixel dimensions, file count, or browser memory are too high.
If generation fails, retry with fewer images, smaller dimensions, JPG/WebP output, or lower quality.
Preview and output
Choose an image first
Output appears in the preview panel after processing.
Use Image DPI Converter to understand how pixel dimensions translate to print size.
Browser canvas export cannot reliably write DPI metadata in every format, so treat this as print planning plus re-export, not a prepress editor.
Print candidates
Check whether an image has enough pixels for a target print size.
Docs graphics
Estimate whether screenshots will remain readable at print size.
Marketing assets
Plan export dimensions before sending to print or design review.
Print check
A 3000 x 2400 image at 300 DPI prints about 10 x 8 inches.
Screen asset
A 1200px screenshot may be fine on web but small for print.
Limit
Use dedicated image software when embedded DPI metadata must be exact.
Confusing DPI with pixels
DPI changes print interpretation; it does not create new detail.
Ignoring target size
Always check pixels, desired print size, and viewing distance together.
Assuming browser export writes DPI
Browser encoders vary and may not preserve or write DPI metadata.
Print estimates
Check if an image is large enough for print.
Documentation
Estimate screenshot readability in exported PDFs.
Asset handoff
Communicate target size and DPI clearly.
Pre-export planning
Resize before sending to a print workflow.
Does Image DPI Converter upload my image?
The public tool is designed for browser-side processing based on the current implementation. Avoid using sensitive images unless you have reviewed the implementation and your own data requirements.
Will metadata be preserved?
Canvas-based exports usually change or remove metadata. Keep the original file when metadata, color profiles, or exact camera details matter.
Why can a browser image tool fail?
Very large files, unusual formats, limited memory, unsupported browser encoders, or SVG features the browser cannot render can cause failures.
When should I use Image DPI Converter?
Use it to estimate print size and understand DPI tradeoffs before resizing or exporting.
