What size should a profile picture be?

Use the platform's current official guidance when available. X recommends 400×400 px. LinkedIn accepts profile photos from 400×400 px up to 7680×4320 px and 8 MB. Slack asks for 512×512 to 1024×1024 px. YouTube renders the picture at 98×98 px and accepts files up to 15 MB. Elsewhere an 800×800 px square is a useful working preset.

How do I make a round profile picture?

Choose "Round PNG" as the format. The download is a square PNG whose corners outside the circle are transparent, so it shows as a circle anywhere, for example on a website or in a slide. Platforms that already crop to a circle only need the square JPG or PNG.

How do I resize a profile picture without cropping it?

Switch the mode to "Fit (no crop)". The whole image is scaled down to fit inside the target size and centered; the empty space is filled with the background colour you pick, or left transparent for PNG. This suits wide logos that would lose their edges in a square crop.

Do I need a different photo for each platform?

Usually not. Keep the subject inside the circular guide and export a high-resolution square master. Use a platform-specific preset only when its current upload guidance calls for one.

Is my photo uploaded to your server?

No. All cropping and resizing happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device.

What file format should I export?

JPEG works best for photos (smaller file size). PNG is better for logos or images with text and transparent backgrounds. Most platforms accept both; YouTube also takes GIF and BMP.

Why does my profile picture look blurry after upload?

A small source image, aggressive zoom, or platform recompression can reduce quality. The small round previews show how much detail survives at avatar size; simplify the crop to the face if it reads poorly at 48 px.

How do I make a 3:4 or 350 × 450 px profile photo?

Type the width and height into the size fields, for example 300 × 400 px for 3:4 or 350 × 450 px when a form asks for that size. The crop box switches to that shape, so you can frame the face before downloading. Check the form for a minimum size, such as 320 × 320 px, before you export.

Profile Picture Resizer

Crop or fit a photo to exact pixels, export it as JPG, PNG or a round transparent PNG, and preview how the avatar looks at small sizes. Processing stays in your browser.

There is no single profile picture size.

Quick answer

There is no single profile picture size. Most platforms take a square image and show it as a circle: X recommends 400 × 400 px, LinkedIn accepts 400 × 400 px up to 7680 × 4320 px, Slack wants 512 to 1024 px, and YouTube renders the picture at 98 × 98 px, so an 800 × 800 px square is a practical master.

Examples

Platform	Size	Basis
X (Twitter)	400 × 400 px, max 2 MB	Official recommendation
LinkedIn	400 × 400 px minimum, max 8 MB	Official
Slack	512 × 512 to 1024 × 1024 px	Official
YouTube	Renders 98 × 98 px, max 15 MB	Official; 800 × 800 export
Instagram, Facebook, TikTok	800 × 800 px	Working preset

Upload a photo, crop or fit it, check the small round previews, and download it at the exact size you need.

Summary

Profile pictures are commonly shown as circles even when the uploaded file is square. This tool gives official sizes where platforms publish them, practical presets elsewhere, an exact custom size, a crop or fit-without-cropping mode, a round transparent PNG export, and live previews at small avatar sizes. Requirements were checked against the linked help pages on October 9, 2026 and can change. Processing is local: the selected image is not uploaded by this tool.

How it works

Choose a platform preset or enter an exact custom width and height.
Upload a JPEG, PNG, or WebP image up to 10 MB.
Crop mode: drag and zoom the crop area, using the circular guide for the safe area. Fit mode: the whole image is scaled into the frame and the gap is filled with your background colour or left transparent.
Check the round previews at 32, 48, 96 and 160 px to see how the avatar reads at small sizes.
Choose JPG, PNG or round PNG and download; the status line shows the output size and file size against common upload limits.
