Image Optimizer
Compress JPEG, PNG, or WebP images, resize large files, and export web-friendly images without leaving the browser.
Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint. TOOLGRID measures tool usage, not the content you enter.

What this tool does
Free web image optimizer for JPG, PNG, and WebP files. Compress images, convert to WebP or JPEG, cap max width, compare before/after file size, and download the optimized result. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Image Optimizer compresses and reformats JPEG, PNG, and WebP files locally using the browser Canvas. Drop an image, choose the output format and quality, optionally cap the max width, then download a smaller file.
The tool is designed as an image optimizer for web images: landing-page screenshots, blog graphics, product photos, newsletter banners, social previews, and documentation assets. Width presets help resize common web assets, and the result panel includes delivery guidance plus a copy-ready image snippet.
The original file is read by the current browser tab, processed in memory, and exported as a new file. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint. Browser-local processing avoids a TOOLGRID upload path, but it is not a blanket security guarantee. This is useful for unpublished product images, client previews, or internal screenshots when you do not want to send them to a third-party remote compressor.
For privacy cleanup before sharing photos, pair it with EXIF Cleaner. For embedding tiny assets in CSS or HTML, use Data URL Generator after optimization.
Where this tool earns its place
Reduce screenshots and article graphics with browser-side processing before publishing.
Turn JPEG or PNG uploads into smaller WebP files for modern storefronts, landing pages, and documentation sites.
Cap max width before uploading a phone or camera photo to a CMS, email template, or support article.
What to check before relying on the result
- Performance and maximum practical input size depend on browser memory, device speed, and the structure of the input.
- Review the generated result before replacing or publishing an original file.

Tips & Tricks
- 01Keep an original copy
Optimization can change compression settings. Keep the original file until you have opened the optimized output and confirmed the size and visual quality tradeoff.
- 02Use WebP for most website images
WebP usually gives smaller files than JPEG or PNG at similar visual quality in modern browsers. Keep JPEG only when older compatibility is required.
- 03Resize camera photos before compressing
A 4000px-wide phone photo is rarely needed on a web page. Capping width often saves more bytes than changing quality alone.
FAQ
02Is my image uploaded to a server?
The image is read into the current tab and compressed with Canvas. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Which format should I pick?
WebP gives the best compression for photos and UI assets. Use JPEG for compatibility and PNG when you need lossless output.
Does quality affect PNG output?
No. PNG is lossless, so the quality slider is ignored. Reduce dimensions with max width instead.
Can I convert PNG or JPEG to WebP?
Yes. Choose WebP as the output format and download the optimized file. Transparent PNGs keep transparency when the browser supports WebP alpha.
Does it help with website image delivery?
Yes. After optimization, the result area shows final dimensions, format, savings, and a simple image tag snippet you can adapt for a CMS, documentation page, or landing page.
Will the tool remove EXIF metadata?
Canvas export typically strips most metadata, but this page is focused on compression and resizing. Use EXIF Cleaner when metadata removal is the main goal.
