How can I reduce the weight of the image without losing too much quality?

Nice day.


I'm still a beginner in using Dreamweaver.

I hope someone can guide me concerning the weight of the image.


The image of the banner currently weighs 1.35 MB (PNG24) - a picture with a logo.

Photography (24 photos on a single page, using the thickbox Gallery) weighs about 1.3 MG each (JPEG images).

Where can I learn how to reduce the weight of

  • the above PNG image

    and

  • the above JPEG images

without losing too much quality?

I would really appreciate guidance.

There are 3 steps to balance weight (file size) vs image image quality

(1) the dimensions of the image (on the screen height x measured in pixels wide is all that matters). Dimensions more small = reduced file size.

(2) compressed file type (JPEG for photographs, PNG, or GIF for everything else). Choose the file type for your picture.

(3) the final compressed image quality - visually by comparing the final image for the file size final vs 'acceptability' (less artifacts)

There are plenty of tutorials online

  • How can I overlap the images without bleeding into one another?

    I read to make diapers and I tried without success. I have a main picture at the top and then want to place another one out of the side which is a little transparent but the upper part of this photo would meet the bottom left of the picture at the top, and they mesh together and bleed. How can I stop this from happening?

    If I understand this: you want to overlap transparent photo on another photo. But the overlap area should show as the picture on top!

    I guess for some reason you do not want to turn off the power of the picture transparency effect to achieve?

    And also you do not want to send the transparent picture to the back of the first photo, as well as for the overlap area only the first image box will show then?

    If this is the case, you can try to use a custom photo shape frame under:

    1. place the two the picture the way you want they overlap at the corners

    2 Select the picture on the top and copy (no need to stick now)

    3. Select two photos, go to the window > object & Layout > Path finder and click on the button subtraction

    You have the picture in the back in a frame under the area of overlap of custom shape

    4. now edit > paste in place

    The transparent picture you copied is now precisely aligned to the custom shape of the first image of the photo

  • How can I reduce the size of a file of numbers?

    I have a file that is too big to 650 MB. It is mostly text. I found 1 sheet which is "inflated".  I tried to copy/paste the columns in a new file, but it ends with lines and additional columns that I copied! It seems to me that if I could have something in layers? How can I reduce the size of the file.

    If it's really just the text that seems really strange.  I repeat what you have already done, copy items to a tim in a new file, and then save after each copy and monitor the size of files.  When you see the file size jump exceptionally fast, do NOT save the new file, and focus on the issue.  What are the benefits?  You paste images into a table as a background fill?

    If you did and you want photos, try to reduce the size of the file by using the menu item "file > advanced > reduce file size...» » :

  • How can I reduce the size of a PSE11 catalog?

    How can I reduce the size and increase the efficiency of a PSE11 catalog by removing many of its elements?

    A catalogue with more than 10,000 photos works very slowly. But deleting the photos does not help. To take an extreme example, removing all but ten photos, remove all tags and identifications of persons and performs the repair and optimization changes size of the catalogue almost at all, from 516 MB to 493 MB. The properties of the two catalogs indicate the number of files to remain unchanged: 10 279 files. (It seems that each of these files is a photo in the original catalogue, great, all except that ten have allegedly been deleted).

    A whole new catalog created with these same ten pictures has less than 1 MB in size, with only 20 files. This tiny catalogue and the 493 MB each probably contain the same usable information.

    Starting with the large catalog with 10,000 photos, is it possible to delete all but ten of his photos, while reducing its size from 516 to 1 MB? (If so, I want to use the same method with a lot more pictures.)

    Thanks for the comments.

    Hi oneidatourism,

    You will need Acrobat to reduce the size of a PDF file. If you do not have Acrobat, you can try it free for 30 days. See www.adobe.com/products/acrobat.html for more information.

    In Acrobat, choose file > save as other > PDF of reduced size.

    Best,
