Pro Tips for Best Results
- Match your image quality settings to the content type — 75–85% JPG quality is ideal for photographs, while PNG should be used at full quality for graphics
- Consider the viewing context when choosing dimensions — mobile screens show images at half the pixel density of desktop, so test at both sizes
- Remove metadata (EXIF data) from images before publishing — this reduces file size slightly and protects location data embedded in photos taken on smartphones
- Schedule image updates regularly — platform requirements change, and an image that meets specifications today may need updating after a platform redesign
- Use the Convert tool at imgresizr.com to change image formats without re-encoding multiple times — each re-encoding cycle reduces quality slightly
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.
Frequently Asked Questions
Why do my images look blurry after uploading?
Blurry images are almost always caused by uploading images that are too small, or by the platform compressing an already-compressed image. Upload at the recommended dimensions and save as JPG at 80–90% quality before uploading.
Are my images safe when using imgresizr.com?
Completely safe. imgresizr.com processes images entirely in your browser — nothing is ever uploaded to any server. Your files remain on your device throughout, ensuring complete privacy and security.
What is the best format to use?
Use JPG for photographs and colourful images — it offers good quality at small file sizes. Use PNG for graphics, logos, and images with transparent areas. Use WebP for the best quality-to-size ratio on modern browsers.
Can I resize multiple images at once?
Yes, you can process images one at a time rapidly using the same settings. The tool retains your settings between images, so batch processing is quick — just upload the next image and click process.
Does the tool work offline?
