Compress & Convert Image — JPG, PNG, WebP & AVIF, In Your Browser
Drop a folder of images, pick a level and an output format, and download them all as one zip — compress, convert between JPG, PNG, WebP and AVIF, compared before/after, done right in your browser.
A quick tool — one slice of free Studio. The same job (and the rest of the edit) lives on the board: multi-track, captions, color, sound, stock. Connect your AI and it edits for you.

Drop as many as you like — they compress in your browser, then download as one zip.
Eziclip is a free, in-browser bulk image compressor and converter: drop many JPG, PNG, WebP or AVIF files at once, choose a compression level and an output format per file, compare original vs result side by side, and download them all as a single zip. It's a web app that runs in your browser, with no watermark and no sign-up. Convert PNG to WebP, JPG to WebP, PNG to JPG or anything to AVIF (where your browser can encode it, e.g. Chrome), or just re-compress in the same format. Unlike TinyPNG (free-tier file limits) or cloud converters that upload your images, Eziclip works in the browser with no caps.
Compress and convert a whole folder at once
Two jobs, one tool. Big images slow down a page, blow past email limits and eat storage, so you compress them. Other times you just need a different format — a PNG converted to WebP for the web, a screenshot to JPG, an old JPG to AVIF for the smallest possible file. The catch with most tools is doing it one file at a time, or sending images off to a server to process.
Eziclip does both in bulk, entirely in your browser. Drop dozens of JPG, PNG, WebP or AVIF files, pick a level and the output format you want, and every one is re-encoded right there. When you're done, download them as a single zip — no watermark, no per-file limit.
Convert between JPG, PNG, WebP and AVIF
Pick the output format per file and this becomes a full image converter. Convert PNG to WebP or PNG to JPG to drop the weight of a heavy PNG, turn a JPG to WebP for the same quality at a smaller size, or convert to AVIF for the smallest files modern browsers support. AVIF is offered wherever your browser can encode it (Chrome, for example); elsewhere WebP is the smallest safe target.
When you convert to a lossless target like PNG, the file can come out bigger than the source — that's a convert doing its job, not a failed compress. When you re-compress in the same format and it can't get any smaller, Eziclip keeps your original rather than handing back a worse copy.
Pick a level, see the result before you save
Three levels cover the common cases: Strong for the smallest file, Medium for the best size-to-quality trade, and Light to keep almost all the detail. Strong and Medium also cap very large images to a sensible size, which is where most of the saving comes from.
Each file shows its before and after size and the percent saved, and a draggable split-screen compare lets you wipe between the original and the result so you can check quality before you download. Choose JPG for universal photos, WebP for the smallest file at the same quality, PNG for lossless, or AVIF where your browser supports it.
Runs right in your browser
Cloud compressors and converters send every image to a server to process it. Eziclip works differently: the work runs in your browser using the same image encoders the browser already ships, so it's a web app rather than an upload-and-wait service.
That's also why it's free with no caps — no file count limit, no queue, and no watermark on the result.
Free, no watermark, no sign-up
Every level, every conversion and every download is free, for everyone — no account, no watermark on the images, no paywall at the zip. Like every Eziclip tool, it's funded by optional support, not by holding your files hostage.
It works on any modern browser, on desktop or phone, and the whole batch downloads in one click as a zip named for the tool, so you can compress or convert a folder and get a folder back.

Questions
Yes. Every level, every conversion and every download is free, with no watermark on the images, no account and no file-count limit — because the work runs in your browser, not on a server.
Right in your browser, using the browser's own image encoders. It's a web app that does the compressing and converting locally rather than sending your files off to a server.
You can convert between JPG, PNG and WebP freely — PNG to WebP, PNG to JPG, JPG to WebP and so on. AVIF is offered as an output wherever your browser can encode it (Chrome, for example); where it can't, WebP is the smallest safe target.
That happens when you convert to a lossless target like PNG — it's a convert doing its job, not a failed compress. When you re-compress in the same format and it can't get any smaller, Eziclip keeps your original instead of handing back a worse copy.
As many as your device can hold in memory — there's no per-batch limit. They process one after another and download together as a single zip.
Medium and Light are visually near-lossless for most photos; Strong trades a little quality for the smallest file. The split-screen compare lets you check each result before you download, and your originals are never changed.
