6 tools Popular picks, from the image converter to everyday utilities
Text Slug Generator Turns titles and product names into lowercase, hyphen-separated, ASCII-only URL slugs. Transliterates accented and special letters and strips punctuation and emoji. Open tool Code HTML Minifier Removes comments and redundant whitespace from HTML while keeping visible text and inline spacing intact. Embedded CSS, JavaScript and JSON-LD blocks are minified in the same pass. Open tool Convert PNG to AVIF Converter Convert transparent product shots, illustrations and heavy PNGs to AVIF. The alpha channel is kept; we explain which PNGs suit AVIF and how to check edges. Open tool Convert BMP to AVIF Converter Encode AVIF directly from the untouched pixels of a bitmap, skipping any JPG in between, for some of the smallest image files you can serve on the web. Open tool QR QR Code Generator: Turn Text and Links Into QR Codes Turn a URL, plain text, Wi-Fi details or a vCard into a QR code that downloads as a PNG. It is built in your browser, with print-size and testing advice below. Open tool Code Base64 Encoder and Decoder Encode text to Base64 or decode it back with full UTF-8 support. Accepts URL-safe Base64, JWT segments and line-wrapped MIME blocks, and warns when the data is a binary file. Open tool

How these free online tools save you steps
No install, no account
Nothing to download and nothing to sign up for. No email address, card details or verification step stands in the way: open a tool page and start working.
36 conversion pages
Every direction between JPG, PNG, WebP, AVIF, GIF and BMP has its own page, and SVG is accepted as a source. Resizing, cropping, rotating and compression share the same queue screen.
More than images
JSON formatter, Base64 and URL encoders, UUID and password generator, QR code generator and reader, CSV to JSON, a redirect checker, PDF merging and splitting: 27 text, code, web and PDF tools sit alongside the image converter.
Format guide
JPG, PNG, WebP or AVIF: which format fits the job?
The format decides file size, transparency and how fast a page loads. Glance at these four cards before you open a converter; most of the time the right target is obvious.
Common questions
Questions about the image converter and other tools
Drop the file onto the JPG to PNG converter; it is processed on our server and the PNG is ready to download within seconds. You can queue 20 files at once and collect them all as a single ZIP. PNG is lossless, so the result keeps the quality the JPG already has. It cannot restore detail that JPG compression removed, though, and the file usually grows.
Lossy compression removes some detail, but at sensible settings the difference is hard to see. The image compressor starts at quality 82; you can pick any value from 20 to 95 or type a target size in KB, which the tool treats as an approximate goal. Output stays in the same format with metadata stripped. Your original file is untouched, so trying another setting costs nothing.
No. Image tools upload your file, process it within that single request and send the result straight back; the temporary copy is deleted when the request ends, and nothing is archived or shared. A ZIP download is deleted as soon as it has been sent. Text and code tools never upload what you type at all. The privacy policy covers the details.
Whenever page speed matters. In lossy mode WebP typically stores the same picture 25-35% smaller than JPG, and it keeps transparency too. Running blog, shop or portfolio images through the JPG to WebP converter before publishing is an easy win. Every current browser opens WebP; keep a JPG copy for email attachments and older desktop software.
Work back from where the image will appear: 1200x630 is common for blog covers and link previews, 1080x1080 for square social posts. The image resizer accepts a width and height of up to 4000 pixels each. Enter only the width and the height follows the original proportions, so nothing gets stretched. If the framing itself needs to change, crop instead of resizing.
Yes. All 67 tools are free, with no card details, trial period, subscription or account. Google ads shown on the pages pay for the site. There are no usage quotas, only per-minute request limits that stop abuse and that normal use never reaches. To get started, open any page in the image tools category.
The image queue takes 20 files at a time. Each file can be up to 24 MB, 50 megapixels and 16,384 pixels on either side. With auto-convert on, files are processed as you add them; with it off, one button starts the whole batch. Collect results one by one, or use the download-all ZIP button that every converter, such as the PNG to WebP converter, provides.
WebP for the widest compatibility, AVIF for the smallest file. At matching visual quality AVIF is usually smaller than WebP, but support in browsers and editing software arrived later and encoding is slower. To decide for your own artwork, convert one image with the WebP to AVIF converter and compare both files side by side, in size and in appearance.
No. It points to the problem instead of guessing a fix. Paste your text into the JSON formatter: valid JSON comes back indented with two spaces, while invalid JSON produces an error message giving the position of the fault. You correct the missing comma or stray quote, then copy the clean result. Everything happens in your browser, so the data never reaches our server.
Length matters more than clever substitutions. The password generator lets you choose 8 to 128 characters, with 16 as the default, and which character types to include. By default every password mixes upper and lower case letters, digits and symbols, and skips look-alike characters such as 0, O, 1, l and I. Randomness comes from the browser's secure generator, and the password never leaves your device. Store a unique one per account in a password manager.
Free, and the codes never expire. The QR code generator writes your text or link directly into the code, with no redirect service in between, so it keeps working even if this site disappears. The code is created on your device and downloads as a PNG of at least 320 pixels. There are no color or logo options, and scans are not tracked.
Yes, with no app to install. Every page runs in a mobile browser: the file picker opens your photos or files, and results land in your downloads folder. Text tools only need copy and paste. The image cropper fixes the framing before you post, and the QR code reader decodes a code from a photo you have taken.
