About this tool
The checks a page-speed audit runs, before you upload
Lighthouse and Search Console tell you an image was too heavy after it is live. This checks it first: the weight against your budget, the pixel width against the width it is actually shown at (allowing for 2× screens), whether the format is the right one for the content, whether EXIF or GPS data is riding along, and whether the filename tells a search engine anything. Every problem links to the tool on this site that fixes it.

Measured, not guessed
Each image is decoded in your browser, so the report uses its real dimensions, real transparency and real metadata — not the filename extension.
Catches location leaks
Phone photos often carry GPS coordinates. The checker flags any image that would publish where it was taken, and the EXIF remover strips it.
Sized for the slot
Tell it how wide the image is displayed and it works out how many pixels you are shipping for nothing — usually the biggest saving of all.
Step by step
How to check images for SEO

Drop your images
Add one image or a whole folder. Each is read in your browser — nothing is uploaded.
Fix what it flags
Each check is Pass, Check or Fix, with a link to the tool that solves it. Copy the report or download it as CSV.

Tips for the best results
- Width matters more than qualityA 4000 px photo shown at 800 px ships 25× the pixels it needs. Resize first; compress second.
- Name files for what they showred-trail-running-shoe.jpg tells Google something. IMG_4031.jpg tells it nothing.
- Strip metadata before publishingEXIF adds weight and can reveal where a photo was taken. It does nothing for SEO.
- Alt text still matters mostThe checker cannot see your HTML. Give every meaningful image alt text that describes it in plain words.

Questions
Questions about this tool
Everything here runs in your browser — nothing you add is uploaded. More in the general FAQ.
What makes an image SEO-friendly?
A descriptive filename, alt text that says what the image shows, a file small enough to load fast, dimensions that match the space it is displayed in, and a modern format such as AVIF or WebP. Page speed is a ranking factor and images are usually the heaviest part of a page, so size and dimensions matter as much as the words.
What is a good file size for website images?
As a rule of thumb, under 200 KB for most content images and under 300–400 KB for a full-width hero, after resizing to the width it is shown at. The checker lets you set your own budget. AVIF reaches these numbers with the most detail intact.
Does image file name matter for SEO?
Yes, a little. Google reads the filename as a hint about what the image shows, especially for image search. Use a few lowercase words separated by hyphens; avoid camera names like IMG_4031, spaces and underscores.
Should I remove EXIF data from images?
For the web, yes. EXIF adds weight, is not used for ranking, and phone photos can contain the exact GPS position where they were taken. The EXIF remover on this site strips it without re-compressing the image.
Are my images uploaded?
No. The images are decoded and measured in your browser with the same APIs a web page uses to display them. Nothing is sent to a server.
