How to Resize a Photo

Click Save All Photos to download. A single photo saves directly; multiple photos are packaged as a ZIP.
Why Use This Resize Tool?
- Batch resizing – upload and resize multiple photos at once; all are bundled into a single ZIP download.
- Three resize modes – exact pixel dimensions, percentage scaling, or popular social media presets.
- Aspect-ratio lock – toggle the lock button to keep proportions intact or freely set any width & height.
- Custom filename postfix – set your own suffix (or none) so saved files never overwrite your originals.
- HEIC support – iPhone photos in HEIC/HEIF format are automatically converted before resizing.
- Works entirely in your browser – your photos are never uploaded to any server.
- Free & unlimited – no signup, no watermarks, no limits.
Resize Modes Explained
The tool offers three tabs to cover different needs:
- By Size – enter an exact width and height in pixels. With the aspect-ratio lock on, changing one dimension automatically updates the other. Turn the lock off to set both dimensions independently.
- By % – scale each photo proportionally. A value of 50% halves the dimensions; 200% doubles them. Useful when you need all photos reduced by the same fraction regardless of their original size.
- Social – choose a platform and format (Instagram, Facebook, Twitter/X, LinkedIn, YouTube, Pinterest) to instantly apply the recommended pixel dimensions for that use case.
Frequently Asked Questions
Yes, the tool is 100% free with no usage limits. You do not need to create an account or provide any payment information.
No. All resizing happens entirely inside your browser using the HTML5 Canvas API. Your images are never sent to any server, so your privacy is fully protected.
Yes. Upload as many photos as you like. Each appears as a thumbnail in the strip at the top of the preview panel. Use Apply to all photos to propagate your current size settings to every photo, then click Save All Photos to download them all as a ZIP.
Reducing an image to a smaller size generally has no visible quality loss. Enlarging beyond the original dimensions will produce some softness because new pixels have to be interpolated — this is a limitation of any resizing tool, not specific to this one.
Yes. HEIC and HEIF files (the default format on modern iPhones) are automatically converted to JPEG in your browser before resizing. A loading indicator is shown during conversion. The saved file will be in JPEG format.
By default, saved files are named originalname-resized.jpg (or .png/.webp). You can change the postfix field to any text you like — for example -800px or -thumb — or leave it empty to save with the original filename.
