Your files never leave your device
Most “free” online tools upload your files to a server, add watermarks, cap file sizes, and drown you in ads. Alvseike does the work right in your browser — so it's private, instant, and free to start.

The upload step was never necessary
Truly private
There's no server to send files to. What you open stays on your machine — by design, not by promise.
Faster in practice
No upload, no queue, no download. Modern browsers run WebAssembly at near-native speed.
One fair price
Every tool in one plan. No per-tool paywalls, no surprise upsells, no ads bankrolling the “free” tier.
Yours to keep
Because the work happens on your device, Pro installs Alvseike as an app that keeps going with no connection at all — a plane, a site visit, a locked-down network.
Formats and alternatives
The decisions that come up before you convert anything, and how Alvseike compares with the tools you may be paying for — each answered plainly.
- WebPvsPNG
WebP vs PNG for web graphics: use WebP for smaller files with transparency, PNG for sharp edges and lossless editing. Convert both in Universal Converter.
Read the answer - WebPvsJPG
WebP beats JPG on file size at similar quality, but JPG still wins on compatibility. Convert and compare both in Alvseike's Universal Converter.
Read the answer - GIFvsMP4
GIFs are larger and slower than MP4s. Use MP4 for most loops, but GIF for simple animations with transparency. Create both with GIF Maker.
Read the answer - PDFvsJPG
PDF vs JPG: choose PDF for documents, JPG for photos. Convert PDF pages to images with Alvseike's PDF to Image tool.
Read the answer - MP4vsWebM
MP4 plays everywhere; WebM is smaller and open. Compare formats and export both locally with Alvseike's Video Compressor.
Read the answer - MOVvsMP4
MOV vs MP4: choose MP4 for sharing, MOV for editing. Convert MOV to MP4 locally with Alvseike's Video Compressor.
Read the answer - LossyvsLossless
Lossy shrinks files by discarding detail; lossless keeps every pixel. Use Image Compressor to compare both before you commit.

Compare JPG and PNG: quality, size, transparency, and when to use each. Convert locally in your browser with Universal Converter.
Read the answer - AVIFvsWebP

Common questions
Is a browser tool really as powerful as a cloud app?
For file work — converting, compressing, cropping, merging — yes. Browsers run WebAssembly, so it happens at near-native speed, and you skip the upload/download round-trip entirely.
What actually happens to my files?
Nothing leaves your device. There is no server to receive them, so there's nothing to leak, sell, or retain.
Do I need to install anything?
No. It's a website — open a tool and start. Nothing to download, no extension required.
Does it work on my phone?
Yes, tools work across devices. A few heavy editors (like the ad builder) are desktop-only, and we tell you clearly when that's the case.
See the difference yourself
Every tool runs free in your browser — no upload, no sign-up, no catch. Try one and watch your file never leave the page.
