White screen image, cut to size.
I got tired of opening an editor to make a blank white canvas. Pick a size, pick a format, download. Or take all five marketplace sizes at once.
White is a decision, not a default
Every white background carries a temperature. Leave it to the camera and a ceramic vase goes cream under tungsten or blue by a north window. Drag the slider and watch the same frame move from 2700 K to 9000 K. Then pick the white that matches how you lit the product.
Twelve whites I actually use
Pure #FFFFFF for marketplace main images. Seamless and studio whites for lifestyle sets. Linen, eggshell and porcelain when a product needs warmth around it. Each opens fullscreen as a backdrop and downloads as an image.
“A white background is not the absence of a background. It is the hardest one to light, and the easiest one to get wrong by five points of grey.”From the studio notebook
Checks I run before an edit
If the monitor is wrong, every white you judge on it is wrong. These take a minute each.
White Background Generator
PNG, JPG or WEBP at any size, plus a five-size batch for marketplaces.
Open toolMonitor Calibration
The near-white patches I use before I trust a screen with an edit.
Open toolDead Pixel Test
Eight flat fields to rule out the monitor before blaming the sensor.
Open toolScreen Resolution Checker
Real pixels and pixel ratio, so exports match the screen.
Open toolScreen Burn-In Test
Grey fields that show retained palettes and toolbars.
Open toolRefresh Rate Test
Checks the frame rate your tethering laptop actually runs.
Open toolWhat sellers ask me
Yes. With the colour set to #FFFFFF the canvas is filled with pure white. PNG and WEBP keep it exact. JPG is lossy in principle, but a flat white field survives compression unchanged in every browser I have tested.
PNG when the file will be edited again or needs to stay exact. JPG when a marketplace asks for it or you want the widest compatibility. WEBP for web pages where file size matters. For a flat colour, all three are small.
One click saves five files, one after another: 2000 × 2000, 1600 × 1600, 1080 × 1080, 1080 × 1350 and 1920 × 1080, in the white and format you have selected. Your browser may ask once for permission to download multiple files.
It is measured, not guessed: the page encodes a scaled copy in your browser and scales the result, so it is exact up to 1024 px and a close estimate above that.
No. Nothing is uploaded. The image is drawn and encoded on your own device.
| Size | I use it for |
|---|---|
| 2000 × 2000 | Marketplace main images with zoom |
| 1600 × 1600 | Lighter square listings |
| 1080 × 1080 | Social square posts |
| 1080 × 1350 | Portrait 4:5 feed posts |
| 1920 × 1080 | Banners, video and slides |
Notes from the table
Marketplace rules, lighting set-ups and the fixes I reach for when white comes out grey.
Phone Photography Using a White Screen
A tablet as backdrop, a laptop as fill, and the phone settings that stop auto-exposure turning white into grey.
RAW vs JPEG When Shooting on White
Highlight headroom, white balance latitude and file handling: what each format gives you on a high-key set.
Removing Shadows From White Backgrounds
Fix it in the light first, then in levels: the order I work in to lose grey backgrounds and keep a natural contact shadow.
