Redimensionner l'image pour Instagram en ligne gratuitement

Crop and resize any photo to the exact pixel dimensions you need — Instagram posts, stories, Twitter headers, LinkedIn banners, or custom print sizes. All processing happens in your browser.

Pourquoi redimensionner les images localement ?

Online image resizers often store your photos on their servers. Our tool resizes your images entirely on your device — your portraits, screenshots, and brand visuals never leave your computer.

Préréglages de taille intégrés

Instagram Post (1080×1080), Instagram Story (1080×1920), Twitter/X Header (1500×500), LinkedIn Banner (1584×396), Facebook Cover (820×312), or enter any custom width and height you need.

Pourquoi optimiser les images avant de les partager en ligne ?

High-resolution photos from modern smartphones can easily exceed 5-10 MB per image. These large files slow down email delivery, exceed social media upload limits, and consume excessive bandwidth. Our image optimization tools compress, resize, and convert your photos directly in the browser.

Image files also contain EXIF metadata including GPS coordinates, camera model, and timestamps. Our tools strip this sensitive information while preserving image quality, ensuring your privacy when sharing photos online.

Formats d'images pris en charge

We support all major image formats: JPG, JPEG, PNG, WebP, HEIC, and TIFF. Whether you need to compress photos for email, resize images for social media, convert HEIC to JPG for Windows compatibility, or embed images as Base64 in HTML — everything happens locally in your browser.

La qualité de l’image sera-t-elle affectée ?

Our compression algorithms use intelligent quality optimization. You can choose between lossy compression (smaller files, minimal quality loss) for web sharing, or lossless compression (preserves 100% quality) for archival purposes. The choice is yours, and everything stays private.
