Can someone who uses Photoshop confirm something for me please. When your doing a “save as” and you then adjust the quality slider it also shows the file size. After you have saved it somewhere can you check to see what the file size is compared to what the quality slider box said it would be? After using Photoshop for about 7 years I’ve just realised that the file size can be quite a bit more than I thought.

Perhaps the file size indicated by the slider is just a guideline?

another way of doing it is use Save for Web. One of the small > icons allows you to specify the exact file size you want. I use this option for all of my web images

I take it you are saving the file for display on the web. If so I find it better to adjust the image size first before saving.

I use "Save for the web" but first adjust the image size to 800x600.

Then use the high jpeg setting in the "save for the web" dialog box.

I know about "save for web" and I always set file size to 250k but I normally like the exif data to go with the file which of course you can't do with"save for web" so its back to "save as" I think.

I never use 'save for the web' (do not like losing the Exif) but just resize to about 800 pixels on the long side and save as a medium jpeg (level 6) file size is usually around 120 kb. There is no need for 250 - 300 kb files for viewing on the web (800 pixel images that is). You will be hard pushed to see the difference between a jpeg quality 4 or 5 and a jpeg quality 12. To answer Dai's question, other than saving and then interrogating the file I do not think you can actually find out what the file size will be.

When posting a piccy on the web, I always save it to my desktop first. If you then right click it and look under properties that will tell you the size.

One of the best ways I have found is have your photographs viewed as thumbnails in Explorer, click on the one you want to edit/resize and take a copy that way. Paste it to whichever folder you want to.

Then open the image in your photo editing software, resize the image by going to Image, Resize, and resize to 800 pixels on the long edge and it should automatically adjust to x 533, so your image to upload will be 800 x 533 (or 600). Then display your image as 'actual size' and do any editing you need ie brightness/contrast/sharpening and only then do the Save. Try 8 on the slider which gives a reasonable quality, or less if you like. Once you have done that, you can easily see how large the file is in explorer by either highlighting it or hover over the image and it gives the info you need.

Hope that helps.

PS, just an extra thought, instead of resizing as above, if you want to crop any unnecessary edges out or even zoom in to a specific part of the photo and crop out the rest, you can set your crop tool to any given size and you know it will come out the same size for any photo you crop, then finish off with the save described above. (If that makes sense lol.)

Dai, as nobody has actually answered your original question I will have a go. As far as I can see there is no way of seeing what the file size actually is in Photoshop after you have done the 'save as' although you can browse to 'Bridge' or or right click in Explorer to get this info.
