Pro Tips for Best Results
- Export at 2× the minimum required dimensions — this provides a buffer against platform compression and retina display scaling
- Use consistent image dimensions across all content in a series — uniformity signals professionalism and builds recognisable brand identity
- Avoid placing important content within 10% of the image edges — platforms may apply cropping, padding, or overlays at the boundaries
- Save a web-optimised version separately from your print version — web images at 72 DPI are much smaller than print images at 300 DPI
- Run images through the Image Compressor at imgresizr.com before any upload — even a 20–30% reduction in file size makes a measurable difference to loading speed
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.
