Free Image Resizer
Resize JPG, PNG or WebP by pixels, percent or ready-made sizes for Instagram, YouTube, X and passport photos — in bulk, free, processed on your device.
Need more than pixels? Upscale a small image 4× with AI, remove the background, or change the scene while keeping the product (first AI edit free).
Keepframe's image resizer changes the size of one or many images (up to 50 at once) in your browser: type exact pixels with or without keeping the aspect ratio, scale by percent, or pick one of 15 presets such as Instagram post 1080×1080, Story 1080×1920, YouTube thumbnail 1280×720 and 2×2 inch passport photo. Choose crop, fit-with-padding or stretch, export JPG, PNG or WebP, and download all as a ZIP. It's free with no sign-up, no watermark and no upload.

FAQ
How do I resize an image for free?
Drop the image, type the new width (height follows automatically with Keep aspect ratio on) and click Resize images. Download the result, or all results as a ZIP.
Can I resize many images at once?
Yes. Add up to 50 images; the same size settings apply to all of them, and Download all saves a ZIP.
What size is an Instagram post or a YouTube thumbnail?
Instagram square posts are 1080×1080, portrait posts 1080×1350, Stories and Reels 1080×1920; YouTube thumbnails are 1280×720. Pick them from Preset size and choose Crop to fill so nothing is stretched.
How do I resize a photo to 2×2 inches for a passport?
Choose the US passport preset (600×600 px, 2×2 in at 300 dpi) with Crop to fill. Check your country's rules for head size and background; this tool only sets the dimensions.
Are my images uploaded?
No. Resizing happens on your device with the browser's canvas, so it also works with private photos and stays fast.
Does resizing reduce quality?
Shrinking keeps images sharp (we downscale in steps for smoother results). Enlarging can only stretch pixels; for real detail use the free AI image upscaler.
How do I reduce the file size instead of the dimensions?
Use the image compressor: set a target such as 100 KB and it finds the best quality that fits.
