☁️BizyAir Image Encode

What it is

This is the plumbing node of the pack, and it's worth understanding why it exists even though it does almost nothing visually interesting on its own. Every other BizyAir node - the Trellis loaders, the IPAdapter nodes, the API wrappers - is a thin client that ships your image data up to SiliconFlow's cloud and brings a result back down. That round trip needs your image encoded into something transportable, and that's exactly what this node does: it takes a standard ComfyUI IMAGE tensor and re-encodes it, then hands you back an IMAGE you can wire into the rest of a BizyAir chain (or just inspect/save on its own).

It's a one-in-one-out utility. If your workflow is entirely local nodes and doesn't touch anything else in this pack, you have no reason to use it - it earns its keep specifically as a prep step ahead of a cloud call.

The inputs that matter

There's really just one decision here:

• image (required) - whatever you're encoding.
• lossless (optional, defaults to false) - the whole point of the node. Off, your image gets compressed lossily before it's sent anywhere, which means a smaller upload and a faster round trip at the cost of some fidelity. On, you keep full quality at the cost of a bigger payload and a slower transfer.

For most workflows, leave it off. The compression artifacts from a single encode pass are rarely visible in the final generated output, and the speed difference adds up if you're iterating. Flip it on when you're doing something where pixel-level fidelity of the input actually matters downstream - style-reference work, product photography, anything where the model is meant to read fine texture detail off the source image rather than just its general content.

Output is a single IMAGE.

How to install it

Through ComfyUI Manager: search "BizyAir," install, restart ComfyUI. Or clone it directly:

cd ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAir.git

Restart afterward. You'll want a BizyAir API key set up before running any node in this pack that actually calls out to the cloud - this particular node doesn't need one to do local encoding, but you'll hit that wall the moment you wire its output into something that does.

Common issues

It looks like it did nothing. For most images at default settings, that's expected - the compression is tuned to be visually negligible. If you need to confirm it's actually re-encoding, compare file sizes or zoom into a high-frequency detail area (fine hair, small text) rather than eyeballing the whole frame.

Unexpectedly finding BizyAir installed. Worth flagging here too since it applies to the whole pack: a period where ComfyUI Manager's missing-node inference misattributed nodes from unrelated packs to BizyAir left some people finding this pack installed without asking for it, and understandably suspicious of an unfamiliar folder with Chinese branding showing up. It's a legitimate node pack from SiliconFlow, the mapping bug was fixed, and if you didn't mean to install it, it's safe to remove from the Manager.

Everything downstream fails. If this node is feeding into another BizyAir node and the chain breaks, the encode step is rarely the culprit - check your API key and account credits first, since that's where cloud-node failures usually originate.
