How to upscale an image 4×

A 4× pass is for when 2× is not enough — print, a zoom crop, or a source that started tiny.

People search “4× upscaler” when they already know the math: they need each side four times larger, not a vague “enhance.” Filvo’s upscaler is the same engine as the main tool. This page preselects 4× so you do not hunt for the control.

4× is heavier than 2× — more pixels, a larger download, and a Pro unlock. If you only need a modest bump for a blog hero, the 2× page is the better default.

4× vs 2× vs a simple resize

Resize in an editor changes the canvas. It does not invent detail. 2× doubles each side. 4× quadruples each side. Neither guarantees a perfect print, but both beat dragging a thumbnail to poster size in Preview.

After a 4× pass, compress a web copy. Do not ship a 20 MB PNG to a category grid.

Steps to run a 4× upscale

Upload a JPG, PNG, or WEBP (up to 20 MB). On Pro, the studio starts a 4× job. On Free, you get 2× and an upgrade path for 4×. Compare with the slider, then download. Crop in the editor only after the enlarge — the model wants as many source pixels as you have.

Frequently asked questions

A 4× pass is for when 2× is not enough — print, a zoom crop, or a source that started tiny.

4× multiplies width and height by four, so a 500×500 photo becomes about 2000×2000 — roughly 16× the pixels. AI fills in the extra detail instead of stretching the original.

Same AI — 2× or 4× already selected.

Cut out, compress, or crop after you enlarge.
