- Export as JPEG, PNG, or WebP with quality control.
- Download one image or a ZIP for multi-image batches.
How to use Resize Image online
Follow these steps to resize a photo or graphic by pixels, percentage, or a platform preset without installing image editing software.
- 1
Add your file
Upload one image or select several files for a batch. Check the original width, height, file name, and preview before changing dimensions or applying a preset.
- 2
Choose resize settings
Enter exact pixels, scale by percentage, or apply a social media preset. Keep aspect ratio locked unless you intentionally need a stretched or fixed-size result.
- 3
Export the result
Select JPEG, PNG, or WebP, adjust quality when the format supports it, preview the new dimensions, then download the current image or the full batch as a ZIP.
Original and resized preview
Compare the source preview with the resized preview and check the displayed pixel dimensions before downloading the final file.
Aspect ratio control
Lock the ratio for proportional resizing or unlock it when the image must fit an exact width and height for a template, form, or placement.
Format and quality output
Export the resized image as JPEG, PNG, or WebP, and use the quality slider to balance file size and visual clarity where supported.
Social media presets
Built-in presets cover common square, story, landscape, cover, thumbnail, pin, and vertical video sizes so you do not have to memorize dimensions.
Browser canvas processing
Resize work happens in the browser session. Large files, many images, and very high output dimensions may take longer on slower devices.
Image Resizer privacy and processing
Image Resizer explains how files move through the browser workspace, what clears after refresh, and what to check before using a resized image.
Processing Browser
Image Resizer reads each file in your browser, draws the resized version on canvas, and lets you preview the new width and height before downloading.
Storage None
Image Resizer keeps selected files only in the active browser session. Refreshing the page clears the previews and resize settings.
Image Resizer account access
Image Resizer can be used without an account. Keep the page open until you have downloaded the resized image or ZIP batch.
Before You Use Resize Image
Review these notes before resizing images for websites, social posts, forms, marketplaces, email, documents, or printed layouts.
Privacy
Image Resizer works in the active browser session and does not need a project account for normal resizing.
Use only images you are allowed to edit, especially when files contain client work, people, product shots, private documents, or unpublished brand assets.
Input Quality
Start from the highest-quality version available. Enlarging a small image can make edges, text, faces, and product details look soft.
If the output must fit a strict frame, check whether resizing alone is enough or whether you should crop first to avoid awkward empty space.
Output
Check the downloaded width, height, format, and visual quality before replacing the original image in a site, listing, post, or document.
Keep the source image until you are sure the resized version has the right dimensions and has not introduced unwanted blur or stretching.
Limits
Very large source files, high output dimensions, and multi-image ZIP exports can use significant browser memory.
Image Resizer downloads count as tool operations. Device memory, source size, and batch size can affect resize speed.
The DPI control is useful for organizing intended output settings, but web images are usually judged by pixel dimensions and displayed file quality.
Questions about Image Resizer
What does Resize Image do?
Image Resizer changes image dimensions by exact pixels, percentage scaling, or social media presets, then exports the reviewed result as JPEG, PNG, or WebP.
Can I resize an image to exact width and height?
Yes. Use Dimensions mode to enter a pixel width and height. Keep aspect ratio locked for proportional resizing or unlock it when a form needs exact dimensions.
Can I resize images for Instagram, YouTube, LinkedIn, or other social platforms?
Yes. Preset mode includes common square, story, landscape, cover, thumbnail, pin, and vertical video sizes that help prepare images for social and publishing workflows.
Does resizing change my source file?
No. It creates a new resized download from the selected source. Keep the original image until you verify the new file dimensions and quality.
Why does a resized image look blurry or stretched?
Blurry output usually comes from enlarging a small source. Stretched output usually means aspect ratio was unlocked or the target frame does not match the original shape.
