The Only Image Resizer
You'll Ever Need

Resize images online for free — no installation, no sign-up, no file uploads to any server. Everything runs instantly in your browser with professional-grade quality.

📋 How to resize an image — step by step

1

Upload your image

Click the upload area above or drag & drop any image file — JPG, PNG, WebP, GIF, BMP, AVIF, or SVG. Your file loads instantly in your browser with zero waiting.

2

Choose your dimensions

Enter a custom width and height in pixels, pick a one-click preset (Instagram, Full HD, 4K, Social OG…), or use the Scale % field to reduce or enlarge by percentage. The aspect ratio lock ensures your image never distorts.

3

Pick your output format & quality

Export as JPG, PNG, or WebP. Drag the quality slider to balance file size vs. sharpness. The live before/after preview shows you exactly what you'll get before downloading.

4

Download your resized image

Click "Resize & Download" and your new image saves instantly to your device. No watermarks, no email required, no limits on how many images you resize.

❓ Frequently asked questions

Is this image resizer really free?▾
Yes — completely free with no hidden costs, no watermarks, and no limits on how many images you resize. There is no premium version. It will always be free.
Does my image get uploaded to a server?▾
No. This tool runs 100% in your browser using JavaScript and HTML5 Canvas. Your image is never sent to any server, never stored, and never seen by anyone except you. It's the most private way to resize images online.
How do I resize an image without losing quality?▾
Set the quality slider to 90–100% and use PNG format for lossless output. When reducing size, use the "Contain" fit mode to preserve the full image without cropping. Avoid enlarging images beyond their original resolution — this causes pixelation no tool can prevent.
How do I resize an image to a specific file size (like under 1MB)?▾
Use the quality slider to reduce file size. Lower quality = smaller file. Switch to JPG or WebP format (not PNG) for the smallest output. The before/after preview shows you the estimated output size live as you adjust.
Can I resize a PNG without losing its transparent background?▾
Yes — select PNG as your output format and transparency is preserved perfectly. If you export as JPG, the transparent areas will fill with the background color you select in the Advanced options.
What's the maximum image size this tool can handle?▾
The tool handles images up to several hundred megabytes and dimensions up to 16,000×16,000 pixels — limited only by your device's available memory. For most use cases including 4K and RAW photos, it works without any issues.
Can I resize multiple images at once?▾
Currently this tool resizes one image at a time for maximum control and quality. Use the "Change image" button to quickly swap to your next image with the same settings applied.
How do I convert JPG to WebP (or PNG to JPG)?▾
Upload any image and simply select your desired output format from the "Output format" dropdown — JPG, PNG, or WebP. Click download and the file saves in the new format automatically.
