FAQs
No. Every resize operation runs entirely inside your browser. Your files never leave your computer and are not sent to any server.
You can import JPG, PNG, WebP, GIF, BMP, and HEIC files (including iPhone photos). For output, you can choose JPG, PNG, or WebP, or keep the same format as the original.
Select the "Target File Size" mode, enter your desired size in KB or MB, then drop your images. The tool automatically adjusts compression quality to match your target as closely as possible. This works with JPG and WebP output. If you select PNG, the tool will convert to JPG automatically since PNG is lossless and cannot be quality-compressed.
For JPG and WebP output, the default 92% quality setting is virtually indistinguishable from the original. PNG output is fully lossless. Making an image larger than the original will not add detail, but will not degrade existing quality.
Fit Within scales your image so that the longest side (width or height) does not exceed the value you enter. The aspect ratio is always preserved. This is useful when you need images to stay within a maximum dimension, for example for social media or email attachments.
Use Exact Dimensions mode and enter the required pixel size (for example 600 x 600 for a US passport photo). Unlock the aspect ratio if your source image has a different shape. You can also use Target File Size mode if the application requires the image to be under a specific size in KB.
No limits. Resize as many files as your device's memory allows. All processing happens locally in your browser.
Yes. HEIC files are decoded locally in your browser. On iOS, Safari may auto-convert HEIC to JPEG before it reaches the browser, which also works. For best results with HEIC files, use Safari on macOS or iOS.
