X / Twitter Image Resizer - Header, Profile, Post & Card Sizes

X in-feed images are 1600 × 900 pixels (16:9), profile photos are 400 × 400, header images are 1500 × 500 (3:1) and link card images are 1200 × 628 (1.91:1). Stay under 5 MB for guaranteed display on every client.

Upload your image, pick the X feed image (1600 × 900), header (1500 × 500), profile photo (400 × 400) or link card (1200 × 628) preset, drag to position the focal point inside the safe area, then download a JPEG or PNG ready to upload.

X shows the centre 16:9 crop in the timeline preview before users click. Keep critical text, faces and product shots inside that centre region — the editor shows a safe-area marker so you can verify the focal point survives the crop.

Yes. X kept the same dimensions as Twitter after the rebrand, so every preset works on both. Older Tweets and embeds using the legacy widths still display correctly because X back-fills smaller renditions automatically.

JPEG at 80–90% quality is the sweet spot for photographs. PNG is better for graphics with text, gradients and transparency where compression artifacts would be visible. WebP is supported by X but JPEG/PNG have wider compatibility for embedded views.

Your image is uploaded to our server over HTTPS to perform the resize, then automatically deleted right after processing — we never store it long-term or share it with anyone, so unreleased campaign visuals, branding work and personal photos stay confidential.

Cover fills the preset frame completely and crops overflow, which suits a header banner where centered content matters most. Contain fits the whole source image inside the frame and pads any gap with your background color, which protects card images and ads where nothing should be cropped off. Stretch forces the exact target dimensions and can distort proportions, so use it only when your source is already close to the target ratio.

Open the background color picker in Settings — it fills the letterboxed space that appears whenever Contain fit can't stretch your image to the full preset dimensions. This matters most for the Card image presets (1200×628 and 800×418), where a mismatched fill color looks unpolished in link previews.

The Format dropdown offers JPG, PNG, WEBP and AVIF; JPG at quality 80-90 (set via the Quality slider) is the reliable default for photos, while PNG — which disables the quality slider since it's always lossless — is better for headers with crisp typography or logos.

On the Profile picture preset, a toggle overlays a circular safe-zone guide on the square canvas so you can verify your face or logo isn't cut off by X's circular avatar crop before you download. Toggle it off any time to preview the plain square image.

Pick the Header/banner preset (1500×500), use Contain fit with a background color that matches your profile theme if your source photo isn't already 3:1, and export as JPG at quality 85-90 to keep the file light while the top of your face or logo stays fully visible.

The Square post image preset is 1080×1080 (1:1) for feed posts that need to look identical whether viewed on X or repurposed on Instagram. Vertical post image is 1080×1350 (4:5 portrait) and takes up more scroll space on mobile, which helps quote cards and portrait photography stand out. Card image (small) is 800×418 — a lighter-weight option at the same 1.91:1 link-preview ratio as the large 1200×628 card, useful when you want a smaller file for the same crop.

Yes, both presets output the exact same 1600×900 (16:9) pixel dimensions — the split exists purely to label your workflow. Pick Single post image when exporting an organic in-feed photo and Ad image when the same file is headed to a Promoted post in Ads Manager, so your exports stay organized by purpose. Fit, background, format and quality all behave identically between the two presets.
