Convert RAR, 7Z and ZIP archives in your browser

Yes. No account, no watermark, no daily cap, no "upgrade to download" at the end. The conversion runs on your own CPU, so there is no server bill for us to pass on to you. The archive converter has no paid tier and no file-size upsell — the only ceiling is how much memory your device can spare.

No. The converter is a WebAssembly engine that downloads once and then runs entirely inside your browser tab. Your archive is read from disk, unpacked in memory and rewritten locally. You do not have to take our word for it: open DevTools, switch to the Network tab, and convert something. You will see no file traffic at all.

Password-protected ZIP files, yes. The converter notices the encryption, prompts you for the password, uses it inside the browser and discards it the moment the job finishes — it is never sent anywhere. Encrypted RAR and 7Z archives are a different matter: unlocking those is not something the in-browser engine can do, so you will need WinRAR or 7-Zip on a desktop for them.

Up to roughly 1 GB converts comfortably on a normal laptop. Past that you will see a warning, because the whole archive has to fit in the browser tab's memory alongside its unpacked contents. 2 GB is a hard stop — anything larger is rejected up front rather than crashing the tab halfway through. If you are close to the limit, closing other tabs genuinely helps.

No — and no browser-based tool can do it honestly. RAR's compression is proprietary, with no open encoder to compile to WebAssembly. 7Z writing is technically possible but unreliable in the browser: the build we would have to ship overflows its output buffer on archives holding already-compressed data. ZipConvert reads both formats and writes ZIP, TAR, TAR.GZ or GZIP instead.

That is the most common use of it. Convert the RAR to ZIP and every operating system — Windows, macOS, Linux, iOS, Android — opens the result by double-clicking, with nothing to install. You get the same files and the same folder structure the RAR contained.

Yes. Safari on iOS and Chrome on Android both run the converter, and the finished archive lands in your usual Downloads or Files location. Phones have far less memory to spare than laptops, so keep mobile jobs to a few hundred megabytes — a 1 GB archive that is fine on a desktop may run out of room on a handset.

Once the page and its engine have loaded, yes. No part of a conversion touches the network, so you can disconnect Wi-Fi mid-job and it will finish normally. To be precise about the limits: ZipConvert has no service worker and is not an installable offline app, so whether the site opens at all on a device that is already offline depends entirely on what your browser kept in its ordinary HTTP cache. Treat offline conversion as reliable, offline loading as a bonus.

Not supported yet. A split archive is one file cut into numbered pieces, and a browser hands us a single file at a time with no reliable way to reassemble them in order. Drop one in and you get a clear message instead of a corrupt output. Join the parts with WinRAR or 7-Zip first, then convert the single joined file here.

Yes. Every converter and tool here works without a login or a payment. No watermark, no daily limit, no "please subscribe to download." There is no paid tier to compare against either: premium subscriptions are on hold, so nothing on the site is held back for a plan you don't have.

No. The archive converter is a WebAssembly engine that downloads once and then runs inside your browser tab, and the image and text tools use the browser's own canvas and JavaScript APIs. Open your browser's Network tab while you convert — you'll see no outbound file traffic. The exceptions are the lookup utilities (WHOIS, DNS, HTTP headers, SSL and email checks), which have to query the internet to answer at all; those send a domain name or an address, never a file.

There's no plan-based cap, because there are no plans. The archive converter warns you past roughly 1 GB and refuses anything over 2 GB, because the whole archive has to fit in the browser tab's memory alongside its unpacked contents. The image tools are bounded the same way — by the memory your device can spare, not by an account.

The converter on this page is archive-only. It reads ZIP, RAR, 7Z, TAR, TAR.GZ, TAR.BZ2, TAR.XZ, GZIP, ISO, CAB, DEB, LHA/LZH and CPIO, and writes ZIP, TAR, TAR.GZ or GZIP. Everything else is a separate tool: image conversions between JPG, PNG, WebP, BMP, GIF, ICO and TIFF; data formats (JSON, CSV, XML, YAML); markup (Markdown, HTML); and stylesheets (CSS, SCSS). There is no audio, video, PDF or Office conversion anywhere on the site — better to tell you now than after you've dropped a file in.

The archive engine is a WebAssembly build of libarchive, paired with JavaScript ZIP and gzip writers. It downloads to your browser the first time you need it and is cached afterwards. When you drop an archive in, the bytes are handed to the WASM module, which runs the same C code a desktop unarchiver would but inside the browser's sandbox; the repacked bytes come back and the browser saves them as a download. The image tools don't need WebAssembly at all — they draw to a canvas and export from it.

No. There is no PDF, video or audio conversion on ZipConvert, and no PDF-to-Word tool. Those need large decoders we haven't shipped, and pretending otherwise would only waste your time. If that's what you need, a desktop tool or a cloud converter is the honest answer.

No fixed count. Drop in as many archives as you like and the converter works through them one at a time — sequentially rather than in parallel, because each job holds an entire archive in memory and running several at once is how you crash a tab. What limits a batch is total memory, not the number of files. Each finished archive gets its own download button; "Download all" saves them individually rather than wrapping them in one ZIP.

No. There's no storage backend and no cloud restore — a converted archive exists only as a blob in your browser tab until you download it, and closing the tab discards it. That cuts both ways: nothing of yours can leak from a server we don't have, and nothing can be recovered if you close the tab before saving.

Two reasons. One: no upload. A 200 MB archive takes roughly 30 seconds to send on a 50 Mbps connection, and ZipConvert skips that step entirely. Two: no shared queue — your CPU is working on your job instead of waiting behind other people's. The trade-off is real, though: a very large archive on a phone will be slower than on a machine built for it.

Not here. Browsers don't decode HEIC natively and we haven't shipped a WebAssembly decoder for it, so the image tools cover JPG, PNG, WebP, BMP, GIF, ICO and TIFF only. On an iPhone, sharing a photo as "Most Compatible," or opening it in Preview on a Mac and exporting, gives you a JPG you can use here.

No. The output is clean — no watermark, no badge, no injected metadata. There's no deliberately degraded free version here, because there's no paid version to upsell you to.
