Will resizing reduce image quality?

Downscaling (making an image smaller) looks great because you are removing pixels rather than generating them, the Canvas API uses high-quality bicubic interpolation. Upscaling beyond 150–200% introduces softness because pixels must be invented. For significant enlargements (2× or more), use our AI Upscale tool, which generates realistic detail rather than just blurring existing pixels.

Can I resize to non-standard dimensions?

Yes. Enter any width and height in pixels. Common presets (1080×1080, 1920×1080, 1200×630, 800×600) are available as quick-select shortcuts, but the input fields accept any positive integer value you type.

Does resizing strip EXIF metadata?

Yes. The browser Canvas API re-encodes the image pixels without preserving EXIF metadata (camera make, GPS location, capture date). If you need metadata intact, for example, keeping the capture date in a photo archive, keep a copy of the original alongside the resized version.

Can I resize multiple images to the same dimensions at once?

Yes. Upload multiple images in one session. All will be resized to the same target dimensions. Download each individually or use "Download All" to get a ZIP archive of all resized files.

What is the difference between resizing in pixels vs percentage?

Pixel mode sets exact dimensions: "800×600 pixels" regardless of the original size. Percentage mode scales relative to the original: "50%" of a 4000×3000 image produces a 2000×1500 result. Use pixel mode for exact platform requirements. Use percentage mode when you just want to make the image smaller without a specific target size.

Will the background become transparent if I resize a PNG?

Yes, transparency is preserved when resizing PNG files. The resized PNG retains the alpha channel from the original. If you download as JPG, transparent areas are filled with white.

Can I resize an image larger than its original size?

Yes, but upscaling introduces blurriness because the tool must create new pixels that did not exist. For clean upscaling, use our AI Upscale tool which uses a Real-ESRGAN neural network to reconstruct realistic texture at 4× the original resolution.

What is Resize Image?

Every platform has its own image-size rules. Instagram wants 1080×1080 for square posts, LinkedIn banners need 1584×396, Etsy product shots should hit 2000×2000, and a standard web hero image targets 1920×1080. Instead of opening Photoshop every time, drop your image here and punch in the exact pixel dimensions you need. The resized file downloads in seconds, and your browser does all the processing. The tool supports pixel-exact dimensions, percentage-based scaling (50%, 75%, 200%), and preset modes for the most common social media platforms. Aspect-ratio locking is on by default, enter one dimension and the other calculates automatically so your image never gets stretched or squashed.

Why use this tool?

Aspect-ratio lock prevents accidental distortion, toggle it on and only one dimension is needed; the other calculates automatically. Processing happens entirely in your browser via the Canvas API. A 15 MP phone photo never leaves your device. Batch mode lets you queue up a whole folder of images and resize them all to the same target dimensions in one pass, then download everything as a ZIP. The tool supports JPG, PNG, WebP, GIF, and BMP input. Output format can be chosen independently, for example, resize a BMP screenshot and save it as a WebP for web use. Quality is adjustable for JPG and WebP outputs.

Common use cases

Resize when an image is too large for an email attachment (most providers cap at 25 MB, and large images load slowly even when they fit), too small for a print job (print requires 300 DPI at the print size, so an 800×600 pixel image only prints cleanly at 2.7×2 inches), or the wrong aspect ratio for a social media post. It is also essential for standardizing headshots across a team page (every photo the same pixel dimensions for a consistent grid), scaling product photos to a uniform size for Shopify, Amazon, or eBay listings, resizing screenshots before inserting into a document, and reducing the file size of phone camera photos before uploading to a form with a size limit.

Pro tips

1For social media, always check the platform's current recommended dimensions, they change periodically. Instagram Stories: 1080×1920. Twitter/X header: 1500×500. Facebook cover: 820×312. LinkedIn post: 1200×627. Using the correct dimensions prevents the platform from cropping or padding your image.
2When resizing product images for e-commerce, enable "Maintain Aspect Ratio" and set only the width. This is faster than manually calculating the correct height for each image with a different aspect ratio.
3If you are resizing images for print, calculate the pixel requirements from the DPI: a 4×6 inch print at 300 DPI requires 1200×1800 pixels. Resizing lower than this will produce a soft print.

How does it compare?

Adobe Photoshop and Lightroom are the professional standards for image resizing but cost $9.99–$54.99/month. PicResize and ResizeImage.net offer free resizing but upload images to their servers. ImageAndPDF.com resizes images entirely in your browser, no server upload, no daily limits, no watermark, and batch processing for free.
