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.

Browser-basedWhat 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.
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 This is useful for unpublished product images, client previews, or internal screenshots when you do not want to send them to a third-party remote compressor.
What you can do with this tool
Reduce screenshots and article graphics with browser-side processing before publishing.
Re-encode JPEG or PNG uploads as WebP for modern storefronts, landing pages, and documentation sites, then compare the actual size and appearance before publishing.
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
- Canvas re-encoding can normalize color profiles, pixels, metadata, compression, and file size.
- An output can be larger than its source; the result panel reports the measured outcome and de-emphasizes that download.
How to use
- 1
Drop an image or pick one from your device.
- 2
Choose output format and quality, and optionally cap the max width.
- 3
Compare original and optimized sizes, then download the result.
Use Cases
Reduce screenshots and article graphics with browser-side processing before publishing.
Re-encode JPEG or PNG uploads as WebP for modern storefronts, landing pages, and documentation sites, then compare the actual size and appearance before publishing.
Cap max width before uploading a phone or camera photo to a CMS, email template, or support article.
Use the final dimensions and generated image snippet as a quick handoff for landing pages, documentation, and CMS publishing.
Tips & Tricks
Optimization can change compression settings. Keep the original file until you have opened the optimized output and confirmed the size and visual quality tradeoff.
WebP can reduce file size for many web images, but the result depends on the source and settings and can be larger. Compare the actual output and keep JPEG when broader compatibility is required.
A 4000px-wide phone photo is rarely needed on a web page. Capping width often saves more bytes than changing quality alone.
FAQ
Is 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?
There is no universally best or smallest format. Compare WebP and JPEG for photographic content, and use PNG when transparency or a non-lossy output codec is required; Canvas can still normalize pixels or color handling, so inspect the result.
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 processing, the result area shows final dimensions, format, actual size change, 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.
