📏 Image Resizer

Use the quality slider approach: resize to your target dimensions first, then if the file is still too large, use the Image Compressor tool afterward to reduce quality. A 1920px wide JPEG at 80% quality is typically 200–400KB depending on complexity.

Use the 'By Width' mode which automatically calculates the correct height to maintain aspect ratio, or enable 'Lock aspect ratio' in Exact Size mode. Never stretch width and height independently unless you intentionally want distortion.

For email attachments, keep images under 1MB. For inline email images, 600px wide at 72–96 DPI is standard. Most email clients display a maximum of 600px wide. Use JPEG at 80–85% quality for photos in emails.

Resize to your maximum display width (typically 1200–1920px for hero images, 600–800px for blog content images, 400px for thumbnails). Use WebP format for smallest file size. Images wider than their display container waste bandwidth.

Currently one image at a time. For batch resizing, process each image separately using the same settings. Each session takes under 10 seconds — reload the page between images.
