How big should website images be?
As wide as they are displayed — rarely more than 1,920 px for full-width banners and 800–1,200 px for content images — and ideally under 200 KB. Oversized hero images are the most common cause of slow pages.
Image compressor: frequently asked questions
Are my images uploaded?
No. Compression happens in your browser using the canvas API, so your images stay on your device.
Which format is smallest?
WebP is usually 25–35% smaller than JPEG at similar quality and is supported by all modern browsers.
What quality should I use?
70–80 is a good balance for photos. Go lower for thumbnails, higher for product close-ups.
Why did my PNG get bigger?
PNG is lossless, so photos saved as PNG are large. Choose WebP or JPEG for photos and keep PNG for logos and screenshots.
Is EXIF data removed?
Yes. Re-encoding drops metadata such as camera details and GPS location, which is good for privacy.
Does compressing images help SEO?
Smaller images load faster, which helps Largest Contentful Paint, one of Google’s Core Web Vitals.
Is there a file size limit?
Images up to 40 MB, limited by your device’s memory.
Can I compress many images at once?
One at a time for now. Batch compression is on our roadmap.
Can I use the output in Figma or CSS?
Yes. Values are standard HEX, RGB, HSL and CSS that work in Figma, CSS and most design tools.
Is the image compressor free?
Yes. It is free with no sign-up and no usage limits for normal use.
