About the Free Online Image Resizer

This free image resizer lets you resize a photo online to any exact pixel dimensions or by percentage — no Photoshop, no app install, no account. It's the fast way to shrink a photo for an email attachment, hit the size limits for a job application or government form upload, prepare a profile picture, or make images for Instagram (1080×1080), Facebook and X link previews (1200×630), or a website hero (1920 wide).

Everything happens locally in your browser using the built-in HTML5 canvas — your image is never uploaded to a server, which makes this one of the most private ways to resize pictures in 2026. That also means it's fast: even a 30 MB photo from a modern phone camera resizes in about a second.

Beyond dimensions, you control the output format and quality. Export to JPG for photos (smallest files), PNG for graphics and screenshots that need crisp edges or transparency, or WebP for the modern web — typically 25–35% smaller than JPG at the same visual quality. The quality slider applies to JPG and WebP, and the tool shows before/after dimensions plus the resulting file size so you can hit targets like "under 2 MB" on the first try.

Working with iPhone photos? Convert them first with the HEIC to JPG converter, or batch-convert site images with the Image to WebP converter.

Image Resizer FAQ

Is this image resizer private and safe to use? ▾

Yes. The resize happens entirely in your browser using the built-in canvas — your photo is never uploaded to a server, so personal pictures and ID scans stay on your device.

Is the image resizer free? ▾

Completely free — no sign-up, no watermark, no daily limit. Resize as many images as you want.

How do I resize an image without stretching it? ▾

Keep the "Lock aspect ratio" box checked. When you change the width, the height adjusts automatically in the same proportion, so the photo never looks squashed or stretched.

Can I resize a photo to an exact size like 1080x1080 for Instagram? ▾

Yes. Use the preset buttons for 1080x1080 (Instagram) or 1200x630 (social link previews), or type any exact width and height in pixels with the aspect lock turned off.

Which output format should I choose — JPG, PNG, or WebP? ▾

Use JPG for photos (smallest files), PNG for screenshots, logos, or anything needing transparency, and WebP for websites since it is typically 25-35% smaller than JPG at the same quality.

Does resizing reduce image quality? ▾

Shrinking an image keeps it sharp; enlarging beyond the original size can look soft because pixels must be invented. For JPG and WebP you also control compression with the quality slider.

Why will my iPhone photo not load in the resizer? ▾

iPhones save photos as HEIC, which browsers cannot draw to canvas directly. Convert it with our free HEIC to JPG converter first, then resize the JPG here.
