How to resize and compress images
- Choose one or more images, or drag them onto the box.
- Pick a preset like Instagram portrait or Amazon product, or enter your own width and height, or scale by percentage.
- If the shape doesn't match, choose whether to fit, crop, pad, or stretch. Drag the slider on the preview to compare the original with the result.
- Choose a format and quality, or enter a maximum file size and the tool finds the best quality that fits.
- Tap Resize and download. One image saves directly; several save together as a ZIP.
When it comes in handy
- Client delivery and proofs. Make web-sized copies of a whole shoot for galleries, previews, and email.
- Social posts. Crop to the exact Instagram, Story, YouTube thumbnail, or link preview size in one step.
- Online shops. Pad product photos onto a white square for Amazon, eBay, Etsy, and Shopify.
- Upload limits. Get photos under a size limit, like 2 MB for a contest entry or 500 KB for a form.
- Faster websites. Convert heavy photos to WebP or AVIF so pages load quickly.
Frequently asked questions
Does resizing lower the quality?
Making an image smaller always removes pixels, but the tool uses high-quality resampling so edges stay sharp. Compression quality is up to you: around 80% is usually indistinguishable from the original on screen while saving a lot of space. Use the compare slider to check before downloading.
Which format should I choose?
JPG works everywhere and suits photos. WebP makes smaller files for websites and is supported by all modern browsers. PNG is lossless and keeps transparency, which suits logos and screenshots but makes large photo files. AVIF is the smallest of all where your browser can create it.
How does the maximum file size work?
The tool tries different quality levels to find the highest one that fits under your limit. If even low quality is too big, it shrinks the dimensions a little at a time until it fits. PNG files can only get smaller by shrinking, since PNG has no quality setting.
What is the difference between crop, fit, and pad?
Fit inside keeps the whole image and makes it fit within the size, so one side may come out shorter. Fill and crop fills the exact size and trims what hangs over, centered. Pad keeps the whole image and fills the leftover space with a background color, which is common for product photos.
Are my photos uploaded?
No. Everything happens in your browser. As a bonus, camera details and GPS location are removed from the resized copies, which is safer for posting online.
Can it open iPhone HEIC photos?
Only in Safari, which can read HEIC. In other browsers, set your iPhone to share photos as JPG (Settings, Camera, Formats, Most Compatible), or export them as JPG first.
