Kwebby's free image tools let you shrink, crop, edit and create images in your browser. The hub lists 13 tools: an optimizer, a cropper, an editor, a reverse image search, and generators for QR codes, favicons, Twitter Cards, color values and donate buttons. Pick a tool, drop in your file or settings and download the result. This page groups the tools by job, shows how to prepare images for a fast page and explains how to use QR codes and image lookups safely.
Key Takeaways
- Kwebby offers 13 free image tools in three groups: optimize and edit, create website assets, and check and test.
- The Image Optimizer compresses JPG, PNG and WebP files in your browser with adjustable quality.
- Google says images are often the largest part of a page's weight, so compress them and write useful alt text.
- The Text to Image Generator turns typed text into a PNG. It is not an AI image generator.
- Scan QR codes only from sources you trust, because scammers hide harmful links in them.
- Use Reverse Image Search to find sources and copies of your own images, never to identify or target a private person.
Optimize and Edit Images
These five tools change the pixels or the size of an image you already have.
- Image Optimizer: Compress JPG, PNG and WebP images in your browser and set the quality yourself.
- Image Crop Tool: Crop to any size or aspect ratio with a drag-and-select box.
- Online Image Editor: Crop, resize, rotate, add filters, text, annotations or a watermark, then export PNG, JPG or WebP.
- Image Effects: Turn a photo into a pencil sketch or apply an edge-detect filter with adjustable intensity.
- Text to Image Generator: Turn text into a downloadable PNG and choose the font, size, color, background and alignment.
Create Website Assets
These four tools make small files and snippets that a site needs.
- Favicon Generator: Create a favicon from text or initials, choose the colors and shape, and download PNG or ICO.
- QR Code Generator: Make QR codes for URLs, text, WiFi and vCards, and download PNG or SVG.
- Twitter Card Generator: Generate Twitter Card meta tags for Summary, Large Image, App and Player cards.
- Donate Button Generator: Generate PayPal donate button HTML with your currency, amount and display name.
Check, Test and Pick Colors
- Reverse Image Search: Upload an image or paste a URL to find its source, similar images and related pages.
- Website Screenshot Generator: Capture a full-page screenshot from a URL.
- Screen Resolution Simulator: Preview a website at different screen sizes without a real device.
- Color Picker & Converter: Pick a color and convert it between HEX, RGB, HSL and HSV, with CSS snippets, complementary colors and shades.
How to Prepare Images for a Fast Page
Follow this order and each step gets easier. Google notes that images are often the largest contributor to overall page size, which can make pages slow and expensive to load.
- Crop to the size you need. Use the Image Crop Tool so you do not ship pixels nobody sees.
- Compress. Run the Image Optimizer and lower the quality until you see a difference, then step back one notch.
- Name the file. Google suggests descriptive file names, such as my-new-black-kitten.jpg, instead of IMG00023.JPG.
- Write alt text. Google calls alt text the most important attribute for giving an image context. Describe the image plainly and avoid keyword stuffing.
- Test the page. Run the Page Speed Checker to see the effect of your changes.
Use QR Codes Safely
A QR code hides the link inside a pattern, so people cannot check it by eye. The FTC warns that scammers cover real QR codes with their own and send codes by text or email, and it advises you to inspect the URL before you open a code in an unexpected place.
When you create a code with the QR Code Generator:
- Test it with your own phone before you print it.
- Point it to a page you control and use HTTPS.
- Add a short line of text near the code that says where it leads.
- Never place a sticker over another company's code.
Use Image Lookups and Generators Responsibly
- Reverse Image Search: Use it to find where your own photos appear or to check the source of an image you want to use. Do not use it to identify a stranger or to track a private person.
- Website Screenshot Generator: Capture pages you own or have permission to copy, and respect the copyright of what you capture.
- Text to Image Generator: It renders your own text as a picture. It does not create new artwork.
- Donate Button Generator: The tool creates HTML for a PayPal button. Test it with your own account before you publish it.

Frequently Asked Questions (FAQs)
How do I compress an image for free?
Open the Image Optimizer, add a JPG, PNG or WebP file, lower the quality slider and download the smaller file. Kwebby says the tool works in your browser with no uploads. Compare the result to the original before you replace it.
Which image formats do Kwebby's tools support?
The Image Optimizer handles JPG, PNG and WebP. The Online Image Editor exports PNG, JPG and WebP, and the Image to Base64 tool accepts PNG, JPG, GIF, WebP and SVG. Each tool page lists what it supports.
Does the Text to Image Generator use AI?
No. It converts the text you type into a downloadable PNG, and you choose the font, size, color, background and alignment. It does not generate new pictures from a prompt.
How does reverse image search work?
You upload an image or paste its URL, and the tool looks for the source, similar images and related pages. Use it to check how your own images are used online, and respect people's privacy.
Are QR codes safe?
A QR code is only as safe as the link inside it. Inspect the URL before you open a code, avoid codes from unsolicited messages and create your own codes only for pages you control.
Final Thoughts
Good images are cropped, compressed, named and described. Start with the Image Optimizer, then use the generators to build the small assets your site needs. For your next step, open the Image Optimizer, compress one image and measure the page again with the Page Speed Checker.
