Is there a best way in photoshop to reduce the image size without losing its quality?

Whenever I reduce the size of the image it seems like a little blurry and reduces its quality. What should I do in order to retain its quality?

Can anyone help me please?

Image>Image Size>Resample Image and choose Bicubic Sharper from the dropdown menu. It had just solved my issue. –  cma May 14 '11 at 1:33

You cannot avoid losing quality when reducing the size of an image; one can hope only to mitigate the quality loss.

When resizing images in Photoshop, the default is to use a softer Bicubic sampler; the comment above to use the Bicubic Sharper would be a good start. It is not, however, always appropriate for all images.

Second, I suggest sticking to multiples of the image width and height. For example, if your original image is 1000x1000, you should get very acceptable results at 250x250, 500x500, 750x750. 398x398, however, is apt to look a bit more blurry.

Hope that helps.

size in px or size in kb ?

if you want to reduced in Kb/Mb :

go to save for web and device from file menu this option wont play with your image,its just reduces the size to some extent to make appropriate for web.

And if you want to reduce it size in PX :

create a document of your desired size for example its 400*400 now drag you desired layer/image to this new document then press cntrl+t,just match the corners from transform corners it wont look blured.. and if you going to make a image of 400*400 to 200*200 it will loose it quality for sure.

Try this.

Before resizing , convert it into smart object.

Right click on the layer of the image ---> Convert it into Smart Object

then resize the smart object using Free Transform tool.

I found it helpful. But there would be a bit of a compromise in image quality.

Note: Do your edit work on the image before you go to smart object. Else you have to raster it again will sure be a loss in quality.

There are a number of options:

  1. Use .gif format, it will reduce the size but if the image has many colours then you will lose quality.
  2. Use .png, it helps but does not reduce the size by much.
  3. Use .webp, a new format introduced by Google. Not researched a lot but will update once I have a tangible answer.

When size decreases we need to compromise bit of quality, however the quality change may be ignorable while comparing with size. There are several steps you can do.

  1. Save as for web (GIF), it will reduce huge size
  2. Crop or resize the document according to requirement.
  3. Choose the quality while saving to reduce the size.

I had a very large (3300px x 2550px).jpg file with a logo that was mainly text. for the webpage I wanted it 150px wide. When resized in photoshop some of the text was completely unreadable.

Not all done in Photoshop, but I imported the original jpg image into inkscape (free vector graphics sw and resized it in there). I then re-saved(exported) it as .png and voila, very little distortion!

Dont know how well it would work for non-text but worth a try.

I had a similar problem with the need to reduce an image so that it could be uploaded to my Social Network profile image and banner.

I tried using iMac's ColorSyynUtility...and although this did reduce the size/pixel...it also drastically reduced the quality.

I was able to overcome my problem by simply importing the image into Microsoft Word...and minimising the image her to my desired size. Then I would take a 'screen shot' of the image and use this image to upload to my Social Networking site.

It worked and the image/s look great! Obviously this would be no good for printing...but for the web it works!

I hope this helps :)

Try Using Windows 7's Paint Tool.. Click on Resize and adjust your height and width according to you. It will not blur your image as well as also reduce your size in kb/mb.

In case of JPG files just try saving them with lower quality JPEG compression. Instead of 90% (which is the default settings for most of the cameras today) save it with something like 68%. You will be unable to notice almost any visible difference, but the file size is almost half!

I recommend this for every photographer. Just set your camera to save images at "eco" quality and you will have much less trouble moving your holiday pictures around and sharing them with friends using flash drives and such. Using something like Faststone Image Viewer you can bulk convert your old photos to around 68% JPEG quality to save a lot of hdd space. This is really much better way then lowering picture resolution.

Create the logo as much as you can big(a4 size will suit) In the print screan , just resize the image using zoom dialog box , or just enter values as you want in size box.

Tc always
