Reducing an Image Size without Losing its Quality

Question

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?

Answer 1

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.

Answer 2

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.

Answer 3

Try this.

Befor 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 a bit compromise would be there.

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

Answer 4

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.
