Resize, compress, and strip metadata from your images in one pass. Set a max size and quality, and download web-ready files. Nothing is uploaded.
How it works
Drop in your images and set a max width/height, a quality, and an output format. Each image is resized down (aspect ratio preserved), recompressed, and stripped of metadata in your browser, with the original and optimized sizes shown side by side. Download individually or all at once.
Everything runs locally. Your images are never uploaded, and there is no signup.
Frequently asked questions
What does the image optimizer do?
It does three things in one pass: resizes an image down to a maximum width/height you set, compresses it at your chosen quality, and strips embedded metadata, the three biggest wins for getting an image web-ready. Everything happens in your browser.
How do resize and quality work together?
Resizing reduces the pixel dimensions (huge phone photos are often far larger than any web slot needs), and quality controls JPG/WebP compression. Resizing usually saves the most, so set a sensible max width first, then tune quality.
What max dimensions should I use?
For full-width web images, 1600-2000px wide is plenty; for blog body images, 1200px; for thumbnails, 400-600px. Leave the fields blank to keep the original dimensions and only compress. Aspect ratio is always preserved.
What is the "PNG (compressed)" format?
Choose it to keep a PNG as a PNG, transparency included, while shrinking it: the image is reduced to a smaller color palette, a lossy step that dramatically cuts size for graphics, logos, and screenshots. The Quality slider sets how many colors to keep. Regular PNG stays lossless. For photos, WebP or JPG is usually smaller.
Does it strip EXIF and location data?
Yes. Re-encoding through the canvas drops EXIF metadata, including camera details and GPS coordinates, which is good for privacy and shaves a little size. The visible image is unchanged.
Can I optimize several images at once?
Yes. Add multiple files and they all get the same resize, quality, and format settings, each with its own before/after size and download, plus Download all.
Are my images uploaded anywhere?
No. All optimizing happens locally in your browser, so nothing leaves your device. No signup, no file-size cap beyond your browser.
