I have a high resolution image (TIFF) that I need to fit in a 320 x 440 px asset for the web (preferably JPEG). The high resolution image is usually a photograph and can sometimes have a logo burned in as well. This asset must also be under 300 kb. How do I keep the file size small enough while also maintaining the highest quality possible (for retina)?

  • Hi. Welcome to GDSE. What image format are you saving the image in? What kind of image is it, such as a photograph, a graphic/logo? When you say "320x440" what is that in, pixels, mm, cm? What have you tried? What has failed? Please edit your question and add the missing information. Thanks. – Billy Kerr Apr 3 at 15:06
  • Have you tried to save a JPG/PNG (whatever you need) and check the file size? – Wolff Apr 3 at 15:14
  • Thank you!! The requirements for the final asset are 300KB 320x440px and I would prefer to save as a JPEG. The original image is a TIFF that is 105.5MB and 7260x4840px (parts of the image will be cropped). I have tried dropping the image into a photoshop file that is 320x440px and then resizing within the artboard. Then I save it for web and check to see if it's under 300KB. The final assets is just so blurry :/ – Kristen M Apr 4 at 18:56
  • Are you remembering to view the final assets at 100% zoom? If you zoom in they will look pixelated/blurry compared to the original. It's hard to tell if there really is an issue with your images or if you are just expecting too much without seeing some examples. – Wolff Apr 6 at 11:28
  • @Wolff I am viewing it at 100%. Unfortunately I can't send any examples because of copyrighting issues but I think you're right in that I may be expecting too much. – Kristen M Apr 8 at 19:50

You should be able to save an image that is 320x440 at max settings and easily get under 300kb if you save as a jpg. If this is your own website, I would save at a lower quality so my web pages load faster.

If you want to save for a retina screen, then you have to export at multiple sizes. So if your image needs to be 320x440, then your 2x image will be 640x880.

See relevant question:

Are @2x images simply larger in terms of height and width or do they actually have a higher PPI (pixel density)?

  • Thank you! We save out our images at 4 breakpoints (Desktop, Tablet, Phablet, Mobile-320x440). The Desktop images under 300kb are 50% quality (so not great), but our mobile images are especially blurry even at 100% quality. – Kristen M Apr 5 at 14:09
