Our Mission – We Made the Tool We Kept Wishing Existed
Changing the DPI of an image shouldn’t require a design degree, a paid subscription, or a 200MB software download. It should just work – in your browser, for free, in seconds.
That’s why we built Oplyse – a clean, fast, completely free DPI converter that runs completely in your browser. No account. No limits. No nonsense.
What Oplyse Does
Oplyse lets you change the DPI of any image quickly and without quality loss. We support multiple file formats – JPEG, PNG, WebP, and many more – so whatever you’re working with, we’ve almost certainly got you covered.
Who It’s For
- Photographers preparing files for print.
- Designers fixing client assets before a deadline.
- Students meeting submission requirements.
- Developers optimizing images for different outputs.
- If you have Googled “how to change image DPI online” and been let down by what you found, Oplyse was built for you.
If any of that sounds familiar, this free online DPI converter was built with exactly your situation in mind.
Our Principles
Free means free. No file limits, or format restrictions behind a paywall, no watermarks. Ever.
Privacy by design. Client-side processing means your files never touch our servers.
Simple by choice. Select your file, set the DPI, download. No tutorial needed.
Multiple formats. Because real-world image work isn’t always tidy.
Based in Denmark 🇩🇰
Oplyse is built and operated in Denmark, within the EU. We take GDPR seriously – not as a checkbox, but because we genuinely care. For legal terms and privacy, visit our Privacy Policy and Terms of Service – they cover everything in plain language.
