Good to know
Sizes from the platforms
Presets follow each platform's own help pages. Where a platform publishes no size, the tool says so.
Circles and safe areas
Profile photos preview as the circle the app shows. Banners and stories mark the area that's never cut off.
Under the size limit
JPGs are compressed to fit a platform's limit, such as 2 MB for a YouTube thumbnail uploaded from the app.
Runs on your device
Your image is cropped and resized in your browser. It's never uploaded.
Frequently asked questions
Which platforms are included?
YouTube, Instagram, Facebook, WhatsApp, X (Twitter), LinkedIn, Pinterest, Snapchat, Telegram, Discord, Twitch and Reddit: profile photos, covers and banners, posts, stories and thumbnails, plus the 1200 × 630 px link preview image websites use.
Why does my profile photo come out square?
Platforms store profile photos as squares and show them as circles. The tool makes a square file and previews the circle, so you can check nothing important sits in the corners.
What is the dashed box?
On covers and stories it marks the part every device shows. YouTube banners show only a central strip on phones and computers, X can trim the top and bottom of a header, and stories put buttons over the top and bottom of the screen.
Should I choose JPG or PNG?
JPG for photos, because the file is much smaller. PNG for logos and graphics with text and sharp edges. Only JPGs are compressed to fit a platform's size limit.
Can I use my own size?
Yes. Choose Custom size at the bottom of the list and type the width and height in pixels.
Is my image uploaded?
No. The image is cropped, resized and saved in your browser, and it never leaves your device.
