Print-Ready DPI Conversion
Adjust metadata without touching pixels, keeping artwork crisp and deliveries consistent.
Non-destructive DPI swap
Rewrite only the DPI metadata so pixel data, compression, and color stay untouched, while print dimensions update instantly to match vendor specs across projects.
Batch conversion control
Queue up to twenty images, apply one target DPI across the set, then download everything at once with filenames that include the new DPI for quick sharing.
Preset + custom targets
Use common presets like 300 DPI or enter a precise custom value for specialty prints, without re-exporting the artwork or recalculating sizes by hand.
Progress transparency
See queued, processing, and completed states with original→target DPI so you can verify each file before sending it to clients or printers with confidence.
Local privacy workflow
All conversion happens in-browser, keeping client assets off servers and compliant with internal security policies and NDA requirements for client work.
ZIP-ready delivery
Grab individual files or a clean ZIP package that keeps filenames organized, making handoff to printers, vendors, or marketplaces painless for approvals.
Convert DPI in Three Steps
Upload, set a target, and export updated files with accurate metadata.
Upload your files
Drag & drop JPG or PNG images and the converter builds a local queue instantly, keeping every file on your device for privacy.
Set the target DPI
Choose a preset or enter a custom value between 72 and 1200 DPI, then confirm the target for the full batch before conversion starts.
Download the outputs
Save single files or a ZIP with DPI-tagged filenames so every asset is ready for print, listing, or delivery right away.
Standardize DPI Before You Deliver
Convert DPI metadata locally and deliver print-ready assets with consistent sizing, clean filenames, and zero uploads from start to finish.
DPI Converter FAQ
Answers to common questions about converting DPI metadata for print-ready files.
No. The converter edits only the metadata tag that defines print size. Pixel width and height stay identical, so sharpness, compression, and file size remain the same unless you later resample the image in another editor.
It works with JPG and PNG files. PNG transparency and embedded ICC profiles are preserved because pixels are not re-encoded. If you have TIFF or RAW, export to JPG or PNG first, then convert the DPI safely. It stays fast.
Most print shops and marketplaces assume 300 DPI when calculating physical size. Setting 300 ensures the previewed dimensions match your intent for posters, labels, and packaging, avoiding surprises during proofing.
No. Files never leave your device. The conversion runs locally in the browser and nothing is uploaded, cached, or retained on our servers, so you can handle client artwork without sharing it or creating an account during reviews.
Each batch uses one target DPI for consistency. If you need multiple outputs, run the converter again with a new target value and download a second set. This keeps filenames clear, reduces mistakes, and makes QA faster.
Converted files keep the original name with the new DPI appended, making it obvious which assets were updated. You can rename files after download, but the suffix helps prevent mix-ups during reviews and approvals later.
The tool overwrites the existing DPI tag with your chosen value. This is useful for legacy files with incorrect settings or when you need to normalize an entire delivery to one print spec across teams. It helps everyone stay aligned.
No. The converter does not re-encode pixels, so PNG transparency and ICC color profiles remain untouched. Only the DPI metadata is updated, keeping visual output identical for screens, proofs, and print across approvals.
Yes. You can use the tool for free without creating an account, entering a credit card, or installing software. There are no usage caps or watermarks, so you can edit as many images as you like and download full-quality results any time.
No. All processing happens locally in your browser, which means files stay on your device and are never sent to our servers. Once you close the tab, nothing is stored on our side, making it safe for personal and client work.
