Why Use This Image Resizer?
25+ Social Media Presets
Every major platform covered: Instagram square (1080×1080), portrait (1080×1350), Story (1080×1920), LinkedIn post (1200×627), X header (1500×500), Pinterest pin (1000×1500), YouTube thumbnail (1280×720), Etsy listing (2000×2000), Shopify product (2048×2048), and many more.
True Batch Processing
Upload 50 photos, select 3 presets, and get 150 resized images in one click. No other free tool processes this many combinations at once without uploading to a server.
Smart Crop Modes
Cover mode crops to fill the exact target size — great for product images. Contain mode fits the whole image with letterboxing — great for logos. Fill stretches to fill — useful for banners.
Zero Quality Loss on PNG
PNG output is lossless — pixel-for-pixel perfect. Use it for screenshots, infographics, logos, and graphics where you can't afford compression artifacts.
Frequently Asked Questions
How many images can I resize at once?⌄
You can upload and resize up to 50 images in a single batch. Each image can be resized to multiple presets simultaneously — so one batch of 10 photos with 3 presets selected produces 30 resized files.
What is the best image size for Instagram in 2025?⌄
Instagram recommends 1080×1080px for square posts, 1080×1350px (4:5) for portrait posts which get more screen real estate, 1080×566px for landscape posts, and 1080×1920px for Stories and Reels.
What is the difference between Cover, Contain, and Fill resize modes?⌄
Cover crops the image to exactly fill the target dimensions while keeping the subject centred — nothing stretches. Contain fits the whole image inside the canvas and adds a white border if needed. Fill stretches the image to exactly match the target, which may distort it.
Are my images uploaded to your server?⌄
No. Every resize operation runs entirely inside your browser using the OffscreenCanvas API. Your files never leave your computer and are never sent to any server.
Can I resize images to a custom size?⌄
Yes. Below the preset grid there is a "Custom Size" input where you can enter any width and height in pixels. Custom sizes work alongside presets — you can select multiple presets and a custom size at the same time.
What output formats are supported?⌄
You can export as JPEG (smallest file size, ideal for photos), PNG (lossless, ideal for graphics and screenshots), or WebP (best compression, modern browsers only).
