Pre-compression (Brotli / Gzip / Zstandard)
We set up static-asset pre-compression: text resources (HTML, CSS, JS, SVG, fonts) are compressed in advance into Brotli, Gzip and, where supported, Zstandard and served already compressed — without on-the-fly server load. So pages are transferred in a smaller volume and load faster. Honestly upfront: this gives a measurable transfer-weight reduction, but requires server access and its format support, and affects the business result only as part of speed.
Pre-compression (Brotli / Gzip / Zstandard) — overview

Pre-compression is a project: we set up advance (pre-) compression of static assets into several formats and correct serving of the right variant by the browser's Accept-Encoding header — Brotli (best for text), Gzip (a universal fallback) and Zstandard where the server and client support it. Unlike on-the-fly compression, pre-compression does not load the CPU on every request and gives the maximum compression level. Honestly about the conditions, this is key: access to the server/web-server config is needed; not all hosting/builders allow this (managed/shared are often limited) — we honestly check and say what is available. Honestly about formats: Brotli and Gzip are supported everywhere; Zstandard on the web is NOT supported by all browsers/servers — it is added as an additional variant with a fallback, not instead of the proven Brotli/Gzip. Honestly about the effect: compression reduces the transfer volume of text resources (measurably, before/after), but does not compress already-compressed formats (images/video — that is separate optimization) and does not speed up a slow server/application. Honestly about business: this is part of speed, we do NOT guarantee sales growth by itself. An important boundary: this is static pre-compression, not image optimization (707), not a CDN (713) and not overall server tuning (722). If good compression is already enabled, the benefit is small. Picture this: instead of serving 'raw' text files the server serves compact compressed versions right away. The base price starts from 12,000 ₽ per project; it depends on the server and stack.
Problems we solve
- Text resources are served uncompressed or weakly compressed.
- On-the-fly compression loads the server CPU.
- Brotli is not used, only basic Gzip.
- A large transfer volume slows loading.

FAQ
Will Zstandard definitely work for me?
Not always. Zstandard on the web is not supported by all browsers and servers. We add it as an additional variant with a fallback to Brotli/Gzip (which work everywhere), not instead of them. If there is no support, Brotli/Gzip will give the win.
Will it speed up the whole site and raise sales?
Compression reduces the transfer volume of text resources (measurably), but does not compress images/video or speed up a slow server/application — those are separate tasks. We do not guarantee sales growth by itself; it is part of overall speed.
Can it be set up on my hosting?
Access to the server/config is needed. On managed/shared hosting and builders this is often limited — we honestly check and say what is available, without promising to set it up where it is impossible.
