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
- Uploading images that are too small: A small image stretched to fill a larger display area becomes visibly blurry. Always start with an image at or above the minimum required dimensions, and resize down rather than up.
- Using the wrong file format: JPG for logos and text overlays causes visible compression artefacts around edges. Use PNG for graphics and any image with a transparent background, and JPG only for photographs.
- Ignoring the aspect ratio: Forcing an image into incorrect dimensions distorts it. Always lock the aspect ratio when resizing, and create platform-specific versions rather than stretching a single image everywhere.
- Compressing too aggressively: Over-compressing creates blocky artefacts that make images look unprofessional. Aim for 75–85% JPG quality as a safe starting point and adjust based on the visual result.
