Practical image guide

Resize images for the place where they will be used

Image resizing and image compression solve different problems. Resizing changes pixel dimensions; compression changes how efficiently those pixels are stored. Start with the best original, make a delivery copy, and keep the master file untouched.

Choose dimensions for the destination

Keep the aspect ratio locked unless the destination explicitly requires a different shape. Unlocking it can stretch faces, circles, and typography.
Use the actual display size as your starting point. Sending a 5000-pixel photo into a 700-pixel content column adds weight without adding visible detail for most visitors.
For high-density screens, a source around twice the CSS display width can help. Do not double every image automatically; compare the visual result and page weight.
When a marketplace or social network publishes exact dimensions or an aspect ratio, follow its current specification and check the final preview.

A reliable five-step workflow

Duplicate the original so an untouched master is always available.
Enter the target width or height and keep proportions locked.
Choose the output format based on transparency, image content, and destination support.
Export once, then inspect text, faces, gradients, and edges at the real display size.
Confirm pixel dimensions and file size in the downloaded result before publishing it.

Pick a format by image type

JPG is usually practical for photographs. It does not support transparency and loses some information each time it is exported, so lower quality gradually and inspect faces and gradients.

PNG is useful for screenshots, diagrams, logos, and transparent graphics. It is lossless, but photographic PNG files can be much larger than an equivalent JPG or WebP file.

WebP is a strong web-delivery option for photographs and transparent graphics. Check that the software or service receiving the file supports it before replacing a JPG or PNG workflow.

What this browser tool can and cannot do

Core image processing happens on your device, so practical file and batch limits depend on browser memory and the device being used.
Downscaling removes pixels. Upscaling interpolates new pixels but cannot restore genuine detail or repair an out-of-focus source.
Changing JPG to PNG cannot restore quality already lost to JPG compression; it only changes how the next copy is stored.
Keep originals for print, archival, legal, or professional work. Treat resized and compressed files as delivery copies.
