Quality checkpoint
- Check faces and edges were not cropped
- Download and inspect output size and sharpness
The calculator, builder or download above works independently. AI Assist is an optional explanation and writing helper, never required to complete the core task.
Resize images for websites without sending files to a server
Oversized images slow pages down, use mobile data and make uploads awkward. The right format and dimensions can deliver a sharp result with much less weight. For most photographs WebP or JPEG works well; PNG is often best for logos and other transparency-sensitive graphics.
Before you start
Choose dimensions for the real display slot, not the original camera size. A small product thumbnail needs different treatment from a full-width hero. JPEG/WebP typically suit photographs; PNG is useful for some transparent graphics.
How to use this tool
- Choose an image from your device. The conversion runs locally in your browser.
- Set the target width and height, keep aspect ratio on when you do not want distortion, and select a format.
- Compare the before and after sizes and download the processed file.
A real-world example
A 4000-pixel-wide product photo may only need to be 1200 pixels wide on a normal website content area.
Check the image visually after compression. A smaller file is not automatically better if it looks damaged.
Check this before you finish
- Keep the aspect ratio unless you deliberately want a crop.
- Inspect fine text, faces and logos after compression.
- Compare actual output bytes instead of trusting a promised saving.
What to avoid
A tiny file with visible artefacts can harm trust just as much as an oversized one harms load time.
WHAT THIS TOOL ACTUALLY DOESDownload the processed image locally; it is not uploaded to the website by default.
Frequently asked questions
Do you upload my photo?
No. This tool resizes the selected image in your browser.
Why did the new file get bigger?
PNG and some quality settings can produce larger output than the original. Try WebP or adjust quality if suitable.
