Resize images online for free without uploading them. Set exact width and height in pixels for JPG, PNG, WebP, GIF, and BMP — for profile photos, product listings, thumbnails, banners, and web layouts that need a specific size.
How to resize image
- Select an image from your device (or drop it onto the upload area).
- Pick a common size (5R, 3×4, A4…) or enter width and height. Enable Keep aspect ratio for proportional scaling.
- Create the resized file and download it.
ConvertPeach reads your image dimensions when you open a file. Everything runs on your device — no account and no remote processing queue.
Why resize image
Resizing to the size you actually need keeps images sharp on screen and lighter to transfer:
- Match platform requirements — many sites and apps expect a specific width, height, or ratio.
- Avoid oversized downloads — a 4000px photo in a 640px column wastes bandwidth.
- Sharper display — downscaling to the right size usually looks better than shipping a huge original.
- Pair with compression — after you set dimensions, Compress Image can shrink the file further.
If you need to cut out a region instead of scaling the whole image, use Crop Image first, then resize.
When to resize image
Use Resize Image when dimensions are the problem:
- A form or CMS asks for an exact size (for example 1200×630 or 1080×1080).
- You need a square avatar, a wide link preview, or a tall story frame.
- Your layout column is much smaller than the original photo.
- You want to downscale before compressing for email or the web.
- You prefer not to upload personal or unreleased images to an online resizer.
Prefer downscaling when the original is larger than you need. Upscale carefully — enlarging cannot invent real detail. Lock aspect ratio unless you intentionally want a different shape.
Common sizes
Exact platform requirements change over time, but these patterns come up often:
- Social square posts — around 1080×1080 for many feeds.
- Landscape shares and link previews — often near 1200×630 or similar wide ratios.
- Story / vertical frames — tall ratios such as 1080×1920.
- Avatars and profile photos — smaller squares (for example 400×400 or 512×512).
- Web content — match your layout column width (or a modest 1.5–2× for sharp retina displays).
Resolution, DPI, and pixels
On screens, what usually matters is pixel width and height, not print DPI. A 2000×1500 image displayed at 500×375 CSS pixels is still a large download. Resize to the pixel size you will actually show, then compress if the file is still heavy.
DPI metadata matters more for print workflows. This tool focuses on changing pixel dimensions for digital use.
Unlike upload-based resizers, ConvertPeach resizes supported images in your browser, so personal photos, unreleased product shots, and screenshots stay on your device.
FAQ
Can I resize to 5R, 3×4, or A4?
Yes. Use the common-size presets for ~5R, 3×4, A4, square, story, and link-preview dimensions, or enter custom width and height in pixels. On screens, pixel size matters more than print DPI.
Can I resize an image without cropping it?
Yes. Resize scales the whole image. Use Crop Image if you want to cut out a square or other region first.
Will resizing stretch my photo?
Not if Keep aspect ratio is on. Turn it off only when you intentionally want a different width and height independently.
Can I resize without losing quality?
Downscaling generally looks fine when you pick sensible target sizes. Extreme upscaling will look soft. Pair resize with Compress Image when you care about file size more than maximum fidelity.
Are my images uploaded to a server?
No. ConvertPeach processes supported images locally in your browser. Your files never leave your device.
Is the image resizer free?
Yes. Every ConvertPeach tool is free to use, with no signup required.
Which formats can I resize?
JPG, PNG, WebP, GIF, and BMP are supported on this page. For HEIC from iPhones, convert with HEIC to JPG first if needed.
Do I need to install software?
No. A modern browser is enough. Processing starts when you choose a file and run the tool.
