About this tool
Shrink photo and graphic file sizes for websites, email, WhatsApp, and app uploads without sending the original file to a remote compression server.
Set a max width or height to fit common layouts (blog heroes, thumbnails, product cards), then tune quality for JPG or WebP until the preview looks sharp enough.
Private by design: resizing and compression run with browser canvas APIs on your device, which is ideal for client drafts, ID scans you should not upload, or unreleased product shots.
Tips for better results
- For web pages, start around 1200–1600px on the long edge and quality near 70–85 for photos.
- Use WebP when your audience’s browsers support it for smaller files; keep JPG for maximum compatibility.
- Choose PNG when you need sharp UI graphics or transparency rather than photographic compression.
- Always compare the preview with the original before replacing a master file — keep originals for archive.
How to use
- 1 Upload an image.
- 2 Set max width, height, format, and quality.
- 3 Download the optimized image.
FAQ
Are images uploaded to a server?
No. Compression and resizing happen locally in your browser.
Which formats are supported?
Most modern browsers support JPG, PNG, and WebP output from this tool.
Can I resize without heavy compression?
Yes. Use PNG, or set JPG/WebP quality near 100 while still capping dimensions.
Will quality look worse after compress?
Lower quality reduces size and can soften detail. Use the preview and raise quality if edges look blocky.
Is there a file size limit?
Limits come from your device and browser memory. Very large RAW-style files may need a desktop editor first.
Can I batch many images?
This page focuses on one clear workflow at a time for reliable previews. Repeat for each image you need.
