Zoom virtual backgrounds: size, format and a clean image

A Zoom virtual background swaps the room behind you for an image or a short video. Zoom does the live part, finding you in every frame; you supply the picture. Zoom is more specific than most meeting apps about what that picture must be: a particular kind of PNG, a size limit, a minimum resolution, and separate rules for video. Get those right and the background is sharp and fills the frame. This guide covers Zoom’s own rules as its help centre states them in September 2026, how to add an image on desktop, mobile and the web client, the green screen option, why text looks reversed only to you, and how to make a clean background when what you want in it (a logo, a product) is stuck in a photo.

Zoom virtual background requirements

From Zoom Support, Changing your virtual background image, checked September 2026:

Some notes on those numbers:

16:9 is the safe shape. Almost every laptop webcam and external camera sends a 16:9 picture. An image of a different shape gets cropped to fit, and what is cropped is usually the edge where you put the logo. 1920 x 1080 is a good default for a photo; 1280 x 720 is enough for a flat colour with a small logo.

24-bit PNG means no transparency. A PNG can store colour only (24-bit) or colour plus an alpha channel for transparency (32-bit). Zoom names the 24-bit kind. A background has nothing behind it to show through anyway, so flatten any transparent areas onto a colour before you upload. What a transparent background is explains the difference in more detail.

15 MB is generous for images. A 1920 x 1080 JPG is usually a small fraction of that. A PNG of a detailed photo can be several megabytes but still fits.

Your device has to be able to run it. Zoom publishes separate virtual background system requirements, with processor lists for Windows, macOS and Linux, and higher requirements for video backgrounds than for images.

How to add a virtual background in Zoom

In the desktop app, before a meeting

1. Sign in to the Zoom desktop app.
2. Click your profile picture, then Settings.
3. Open the Video & effects tab, then the Virtual backgrounds tab.
4. Click a background to use it, or click the add icon to upload your own image or video.

During a meeting

1. Click the arrow next to the video icon.
2. Choose Video & effect settings.
3. Open Virtual backgrounds and choose or upload a background.

On a phone

During a meeting, tap More, then Settings, then Virtual backgrounds, and tap the plus icon to upload an image. On iOS you can also set it outside a meeting from Settings, Video & effects, Background & effects.

In the web client

Join the meeting, click the arrow next to Start Video or Stop Video, choose Choose Background, and use the add icon to upload.

To turn a background off, choose None, or Blur to blur the real room instead.

The green screen option

Zoom’s settings include an I have a green screen toggle. Zoom says to use it only with a physical green screen, with uniform lighting and colour and a solid background. With it on, click your video to pick the exact screen colour.

A green screen gives a cleaner edge around hair and hands, because the app is replacing one known colour rather than guessing where you end. It also has a well-known side effect: anything you wear in that colour disappears too. Without a real screen, leave the toggle off.

Why text in your background looks backwards

You upload a background with your company name and, in your own preview, the letters read right to left. Nothing is wrong with the file.

Zoom’s Mirror my video setting (in Settings, Video & effects) horizontally flips your preview, the way a mirror does, so that raising your right hand looks natural to you. Zoom’s settings article says it only affects how you see your video. Everyone else in the meeting sees you, and the text behind you, the right way round.

So do not flip the image to fix it. If you do, it will read correctly to you and backwards to everyone else. If the reversed preview bothers you, untick Mirror my video and your own view will match what others see.

Making a clean virtual background

The best backgrounds are calm. You sit in the middle of the frame, so the middle should be quiet.

• A flat colour with a small logo looks intentional and reads the same on every screen. Put the logo in an upper corner, because your head covers the centre.
• A tidy photo of a real space, taken from where your camera sits, looks natural because the perspective matches.
• Low contrast behind your head. Strong patterns make the live edge around you more noticeable.
• Brightness close to your room. A bright beach behind a face lit by a desk lamp looks pasted on.

Putting a logo on a colour with a cutout

The logo you want is often only available as a photo of a sign, a printed page or a JPG with a white box. A background remover lifts it off.

1. Drop the photo or image of the logo on getPNG. The background is removed in your browser at the full resolution of the original.
2. Drag the divider in the compare view along the edge. If a rim of the old background shows, use Clean edge colour, and Edge shift to pull the outline in by a pixel or two.
3. Pick your brand colour as the background. This is what turns the cutout into a 24-bit image with no transparency, as Zoom asks.
4. In Sizes, choose the YouTube thumbnail canvas: it is 1280 x 720, which is 16:9 and exactly Zoom’s minimum. Fit the logo inside a margin and drag it to an upper corner. The preview is the file.
5. Save as JPG or PNG on that colour and upload it with the add icon in Zoom.

The logo is never enlarged beyond its own pixels, so a logo from a small file stays small on the canvas. For a bigger logo, start from a larger photo, or build the background in an editor at 1920 x 1080. A logo photo to a transparent PNG covers getting a clean logo from a photo.

Video backgrounds

Zoom also takes a short video as a background: MP4 or MOV, from 360p up to 1080p. A slow loop (clouds, a quiet office, a gentle brand animation) works; fast movement behind you is tiring to watch. Video backgrounds need more processing power than images, and Zoom’s system requirements list higher processors for them. If your call starts stuttering, go back to an image.

When this does not work

• No Virtual backgrounds tab. The setting may be turned off for your account or by your admin, your app may be older than Zoom’s minimum version, or your computer may not meet the system requirements. Check the setting in the Zoom web portal and update the app.
• Zoom rejects the file. Check it is a JPG or a PNG under 15 MB. A transparent PNG, or a format such as WebP, HEIC or AVIF, is the wrong kind of file: save it again as JPG, or as PNG on a solid colour.
• Black or odd areas where the image should be. Transparent areas in a PNG have nothing to show. Put the cutout on a colour before uploading; why a PNG shows a black or white background explains what apps do with transparency.
• The edges of the image are cut off. The image is not the same shape as your camera picture. Make it 16:9 and keep important parts away from the edges.
• The background looks soft. It is smaller than the video it fills. Use at least 1280 x 720, and 1920 x 1080 for a photo.
• Your hair or hands vanish into the background. That is live separation struggling, often because your clothes or hair are close in colour to the room. Better light helps most; a real green screen with the toggle on helps more.
• Text reversed in your preview. Not a fault: see the mirror setting above.

For the same background in Microsoft Teams, which states fewer rules but has its own quirks, see the custom Teams background guide.

Privacy: what goes into the background

Backgrounds often start from internal material: a logo still in draft, an office photo with a whiteboard in shot, a product before launch. Most online background removers and editors upload the file to their own servers. getPNG removes the background inside your browser and the picture is never sent anywhere; after the first picture, it keeps working with the connection switched off.

The steps, in short

1. Make or pick a 16:9 image. Build it at 1920 x 1080 or 1280 x 720 pixels, the shape of most webcam pictures, so nothing important is cropped away.
2. Save it as JPG or a PNG without transparency. Zoom accepts 24-bit PNG or JPG up to 15 MB. A 24-bit PNG has no transparency, so put any cutout on a solid colour before saving.
3. Open the virtual background settings. In the Zoom desktop app, click your profile picture, then Settings, the Video & effects tab and the Virtual backgrounds tab.
4. Add your image. Click the add icon and choose the image (or an MP4 or MOV video) from your computer, then select it.
5. Turn on I have a green screen only if you have one. With a physical green screen and even lighting, the toggle gives a cleaner edge; click your video to pick the screen colour.
6. Check the text direction. If text in the background looks reversed in your own preview, that is Mirror my video, which only changes your view. Others see it the right way round.

Questions

What size should a Zoom virtual background be?

Zoom recommends cropping the image to your camera's aspect ratio. For a 16:9 camera, 1280 x 720 or 1920 x 1080 pixels works, and if you are not sure of the ratio Zoom says to use at least 1280 x 720 (Zoom Support, checked September 2026).

What file types does Zoom accept for a virtual background?

Images must be 24-bit PNG or JPG/JPEG, up to 15 MB. Videos must be MP4 or MOV, with a resolution between 480 x 360 (360p) and 1920 x 1080 (1080p).

Can I use a transparent PNG as a Zoom background?

Zoom asks for a 24-bit PNG, which is a PNG with no alpha channel, so a transparent PNG is the wrong kind of file. If your background is a cutout, such as a logo, place it on a solid colour and save it without transparency first.

Why is the text in my Zoom background backwards?

Your own preview is mirrored. Zoom's Mirror my video setting horizontally flips your video preview and, in Zoom's words, only affects how you see your video. Other participants see the text the right way round, so do not flip the image.

Why is there no virtual background option in Zoom?

Your device may not meet Zoom's virtual background system requirements, the Virtual background setting may be turned off for your account or by your admin, or the app may be older than Zoom's minimum version. Check the setting in the Zoom web portal and update the app.

Do I need a green screen for a Zoom virtual background?

Not on most computers that meet Zoom's requirements; Zoom separates you from the room without one. A physical green screen with even lighting gives a cleaner edge, and Zoom's system requirements page lists it for some Linux setups. Turn on I have a green screen only when you actually have one.
