Free Online Image Resizer – Questions & Answers

Why should I choose Exact Image Resizer over competitor sites?
Most online resizers upload your photos to remote servers (where they sit for hours) and clutter the page with intrusive ads. Exact Image Resizer processes everything 100% locally in your browser with zero latency, complete privacy, and no ads.
Can I lock the aspect ratio so my photo does not stretch?
Yes, the aspect ratio lock is enabled by default. Entering a new width automatically recalculates the proportional height.
What image formats can I upload and download?
You can upload JPG, PNG, WebP, and AVIF/HEIC (on supported browsers), and export to JPG, PNG, or WebP.
Does it work offline?
Once the page is loaded in your browser, the image resizing engine can run entirely offline without an active internet connection.
