Pro Tips for Best Results
- Choose WebP format for web use when browser support allows — WebP files are typically 25–35% smaller than equivalent JPG files at the same visual quality
- Convert images to the correct colour profile for their destination — sRGB for web and screen display, CMYK only for print production
- Use the Crop tool at imgresizr.com to set the exact aspect ratio before resizing — this prevents unwanted squashing or stretching
- Batch process multiple images in the same session rather than processing one at a time — the tool retains your settings between images
- Avoid screenshots for images that will be displayed at large sizes — screenshots are typically 72 DPI and look blurry when scaled up
Common Mistakes to Avoid
- Exceeding the platform file size limit: Platforms reject uploads that exceed their file size limits, which wastes time. Always check the limit before uploading and use the Compress tool at imgresizr.com to reduce file size without visible quality loss.
- Using screenshots as source images: Screenshots are typically 72 DPI and look blurry when scaled up. For print or large-format display, always source the highest-resolution original available rather than capturing a screenshot.
- Applying filters before resizing: Applying colour filters or adjustments before you have finalised the dimensions can cause the image to look different after resizing. Always set dimensions first, then apply colour adjustments last.
- Forgetting to test on different devices: The same image can look noticeably different on an older screen versus a modern retina display. Testing on multiple devices before publishing prevents unpleasant surprises.
