Every platform has different image size requirements. Your LinkedIn photo needs to be 400x400px, your Instagram post 1080x1080px, and your website banner 1920x600px. Resizing images manually in Photoshop is overkill for most people.
Here's how to resize any image to exact dimensions in seconds — for free.

Tips for Resizing Without Losing Quality
Start with the largest version
Always resize down, not up. Enlarging a small image creates pixelation. If you have a 3000px original, resize it down to 1080px — not the other way around.
Keep aspect ratio locked
Changing width and height independently stretches the image. Keep the aspect ratio locked unless you specifically want to change proportions (e.g., making a landscape photo into a square crop).
Use the right format
For photos, JPG gives the best file size. For graphics with transparency, use PNG. For web use, WebP offers the best compression.
After Resizing
- Compress Image — further reduce file size for web
- Crop Image — trim to exact proportions
- Convert Image — switch between JPG, PNG, WebP
- Image to PDF — turn your resized image into a document
