What makes these free online tools quicker to finish

One queue, one batch

Drop up to 20 files at once. Converting and compressing share the same queue, so you can work through files individually or send the whole batch through and collect every result.

No install, no account

Nothing to download and nothing to register for. Open a page, drop the file, take the output. No email address, no card details, no verification step in the way.

36 format pairs

Every combination between JPG, PNG, WebP, AVIF, GIF, BMP and SVG has its own page, and resizing, cropping, rotating and compression live in the same interface.

More than pictures

JSON formatter, Base64 and URL encoders, UUID and password generator, QR code generator, slug builder and character counter: 23 text, code and web utilities.

Format guide

JPG, PNG, WebP or AVIF: which image format to pick

Format choice drives page speed, visual quality and file weight. Skim this before you open a converter and you will already know which of the 36 pairs your file actually needs.

JPG Best for photographs and frames full of colour gradients. No transparency, and heavy files still want a pass through the compressor.
PNG The pick for logos, icons, screenshots and anything needing a transparent background. Sharp edges survive intact; file size grows.
WebP The most balanced choice for the web. A WebP converter hands back a noticeably lighter file with no quality loss you can see.
AVIF The strongest compression of the four in current browsers. Keep a WebP or JPG copy around when older browsers still matter.
Common questions

Questions about the converters and the other tools

Drop the file onto the JPG to PNG converter and the queue hands back a downloadable PNG within seconds. Up to 20 images can go in at once, converted individually or in a single batch. PNG is the right target when you need transparency or crisp edges; a photograph with no transparent area simply keeps the background it already has.

Lossy compression does drop some detail, but at sensible settings you will not spot it. The image compressor lets you set a quality value yourself, or name a target size in KB and let the tool find the setting for you. Somewhere around 75 to 85 suits most photographs. Your original never leaves the machine, so a second attempt costs nothing.

No. A file lives in memory only while it is being processed, and the temporary copy is discarded the moment the output reaches you. We do not inspect the contents, archive them, or pass anything to third parties, and the same holds for personal or work documents. The privacy policy spells out the detail.

WebP stores the same picture in a markedly smaller file than JPG or PNG, and that lands directly on your page speed. Running site, blog or shop images through the JPG to WebP converter before publishing is a habit worth building. Every current browser reads WebP, so keep a JPG copy only when very old devices still matter to you.

Start from where the picture will live: 1200x630 for a blog cover, 800x800 for a product card, 1080x1080 for a social post. The image resizer offers those presets and accepts custom width and height as well. Leave the aspect ratio locked unless you want distortion, and crop instead of resizing when the framing itself has to change.

Yes, all 63 of them, with no card details, no trial window and no subscription. Advertising keeps the site running, which is why there are no usage quotas on conversion, compression or the text utilities. There is nothing to register for either: open any page under image tools and start working straight away.

Image tools accept up to 20 files in one queue, and the per-file size cap is printed on every tool screen. Convert them one at a time, or launch the batch and let the downloads arrive in order. Pages such as the PNG to WebP converter share that same queue, so settings never need rebuilding for each file.

AVIF usually beats WebP on file size at matching quality, though browser support arrived more recently. Choose WebP for the widest compatibility and AVIF when the smallest possible file wins the argument. To settle it for your own artwork, push one frame through the WebP to AVIF converter and compare the two file sizes side by side.

It indents your JSON and reports where the syntax breaks, but it will not invent the missing comma on your behalf. Paste the text into the JSON formatter, read the error position, correct it, then copy the clean output. It is a quick way to sanity-check API responses and configuration files before they ship.

Length beats cleverness: sixteen characters or more, mixing upper and lower case with digits and symbols, defeats the attacks that matter. The password generator lets you set the length and the character rules, then returns a fresh string instantly. Keep it in a password manager and never reuse the same one across two accounts.

Free, and they never expire. The QR code generator writes your text, link or contact details straight into the code itself, so no redirect service sits in the middle and nothing breaks if this page disappears tomorrow. Download the image and print it on a menu, a label or a business card. No scan tracking either.

They do. Every page runs in a mobile browser: the file picker opens your gallery and the result lands in Downloads. There is no app to install anywhere. Text tools rely on copy and paste, image tools on a single-tap upload. The image cropper, for instance, is enough to fix the framing before you post.
