Combined pixel and KB limits
Limit maximum width or height to prevent oversized dimensions, while guiding the file toward your target KB ceiling.
Resize and compress images
Set maximum pixel dimensions and a target KB ceiling together. Review actual dimensions and encoded bytes in your browser.

Your images stay on your device. No uploads.
How to resize and compress images
Select up to 12 JPEG, PNG, or static WebP images from your device.
Set optional maximum width or height limits and a target KB ceiling for the batch.
Start processing, review final dimensions and KB for each image, and download.
Independent verification
Every successful image is measured after encoding. If an image cannot meet both constraints, it is reported as a failure rather than returned oversized.
Private and local
Processing runs directly in your browser. Photos are never uploaded to a server.
Frequently asked questions
How do maximum dimension limits and KB limits work together?
For example, given a 1600×1200 image, setting maximum width to 1200 px (or both maximum width 1200 and height 900 px) initially caps dimensions at 1200×900 proportionally without upscaling. Compression then adjusts quality; if tighter KB targets cannot be met by quality tuning alone, dimensions may be scaled down further. The resulting file may be smaller than the target.
What if my image is below 100 KB, but dimensions are too large?
The tool checks both constraints independently. Even if the file is already small (such as an image below 100 KB), exceeding the maximum width or height triggers re-encoding to fit the bounds, which also strips EXIF.
Does setting maximum width and height create exact dimensions or a square?
No. Maximum width and height define bounding limits; images are scaled down proportionally to fit inside without distortion or square cropping. If a portal requires an exact square or fixed aspect ratio, use the Crop images tool before compressing.
What happens if I turn on Keep original dimensions?
Setting maximum width or height directly conflicts with Keep original dimensions. Setting both displays a conflict and prevents starting; turn off Keep original dimensions or clear all pixel bounds to proceed, and your inputs remain in place for editing.
Does this tool guarantee compliance with official passport or visa specs?
No. This tool only validates against the numbers you enter. It does not verify official requirements such as head-to-chin ratios, specific DPI metadata, or government background rules. Always check official guidelines and your final output.
Can I batch resize and compress JPG and PNG images together?
Yes. You can batch resize and compress JPG, PNG, and static WebP images (up to 12 files at once). Each image is processed independently against the target KB and maximum pixel bounds.
Two different constraints in one workflow
Pixel dimensions define image resolution, while KB measures file storage. Reducing pixel dimensions helps lower file size, but JPEG/WebP quality adjustments also play a role. When both constraints are specified, maximum pixel limits are applied first without upscaling, followed by quality compression to satisfy your KB target.
