Pro Tips for Best Results
- Always work from the highest-resolution original file available — resizing down preserves quality, but resizing up cannot recover lost detail
- Use descriptive filenames before uploading — platforms and search engines use filenames as ranking signals for image discovery
- Compress images to the smallest acceptable file size before uploading — platforms apply their own compression, so starting smaller reduces compound quality loss
- Test your images on both desktop and mobile before publishing — the same image can look significantly different across screen sizes
- Keep original files in a separate folder — never overwrite originals with processed versions so you can always start again if needed
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.
