Image Size Checker Pro

Audits the images on a page and compresses them as drop-in replacements: same file format, same pixel dimensions, same filename.

• Flags heavy files, oversized or upscaled images, and distorted aspect ratios
• Catches missing alt, missing width/height, and lazy-loading above the fold
• Lossless PNG and SVG compression, high-quality JPEG and WebP
• Resizes to 1x and 2x with ready-to-paste srcset snippets

Pageful

Saves an entire web page as one image, top to bottom, including the parts you have to scroll to see. Crop it, stamp it, copy it, or download it. Free, with no account and no network requests.

• Captures inner scroll areas, lazy-loaded images, and virtualized lists without repeats at the joins
• Grabs just one element or a dragged area, even when it's taller than the screen
• Crop, add the page address and date, copy, or download as PNG, JPEG, WebP, or PDF
• Works from the toolbar, the right-click menu, Alt+Shift+S, or Alt+Shift+E

Field Day

Fills out web forms with realistic fake data, then submits them, so you can check that a form works without typing the same details over and over. Free, with no account and no tracking.

• Believable names, emails, phones, and addresses, plus random picks in dropdowns, radios, and checkboxes
• Clicks through multi-step forms and works on forms embedded from other sites, like HubSpot
• Pauses for CAPTCHAs, skips honeypot fields, and maps conditional fields so every branch gets tested
• Set an email pattern like qa+{random}@yourdomain.com so test submissions are easy to filter
