Image Resizer

Key features

• Four resize modes: scale by percentage, limit width, limit height, or fit entirely inside a W × H box.
• Bulk queue with no file-count cap; every file is decoded, resized and re-encoded independently.
• A live example read-out shows exactly what the current rule does to the first image before you process.
• Exports as PNG, JPEG or WEBP, with a quality slider for the lossy formats.
• Real counters, Pause/Resume/Cancel, and Retry Failed for files that could not be decoded.
• Every completed row shows its true output dimensions, so you can verify results at a glance.

How it works

1. 1

   Add Your Images

   Drop one or hundreds. The tool decodes the first file to preview the rule's effect on its real dimensions.

2. 2

   Choose A Size Rule

   Percent scale for quick shrinks, max width/height to cap one side, or fit-within-a-box for uniform dimensions.

3. 3

   Pick Format And Quality

   PNG, JPEG or WEBP output with a quality slider for the lossy two.

4. 4

   Process And Download

   Run the queue, check per-file dimensions, then save individually or download everything as one ZIP.

Tips for better results

• 💡Downscaling (a 4000px camera photo to 1600px for the web) looks great; extreme upscaling cannot invent detail that was never captured.
• 💡Max width/height modes never upscale — smaller images pass through at their original size.
• 💡Each output side is capped at 8192 px.
• 💡JPEG output fills transparent areas with white, same as the Image Converter.
