Resize JPG Online
Resize JPG online by width and height, percentage or a canvas preset. Keep proportions locked for natural-looking photographs and export in JPEG format. Resizing changes pixel dimensions; use the compressor separately when you need a specific byte limit.

Set JPEG dimensions for the receiving layout
Resizing JPG changes a photograph's pixel dimensions. A percentage scales from its source size; pixel controls help meet a known width or height. Preserve proportions when stretching would distort faces or objects. JPEG export also uses lossy encoding, so start with the original photograph and review the resized result at the intended display size.
Compress the resized JPEG when it meets the dimension requirement but still weighs too much.
How to use Resize JPG

Add up to 20 JPG or JPEG photos.
Review settings
Choose pixels or percentage and keep the aspect ratio locked. Use a canvas preset when a fixed frame is required.
Save results
Resize, check the resulting dimensions and framing, and download the JPEG files.
Tips for Resize JPG
Choose dimensions for the destination rather than enlarging every image. Upscaling adds pixels without recovering missing detail. Contain-fit presets preserve the whole photograph and fill unused space with a background; crop first for an edge-to-edge frame.
A 2400 × 1600 JPEG resized to 50% becomes 1200 × 800. A 1080 × 1080 canvas instead fits the full photograph inside a square, with background space above and below.

Resize JPG: frequently asked questions
What to know before you go.
How do I keep a JPG from stretching?
Keep the aspect ratio locked in pixel mode or resize by percentage. A contain-fit canvas keeps the full image proportional.
Does resizing a JPEG guarantee a smaller file?
No. Dimensions and encoding both affect bytes. Review the output size and use Compress JPG for a separate byte target.
Can I enlarge a JPG photo?
Yes, but the added pixels do not recreate real detail and the photograph may look softer.
Can a square preset crop my JPG automatically?
The presets use contain fit with background space. Crop your photo first if you want a square that fills the frame.
Does entering a width guarantee a specific JPG file size?
No. Width specifies pixels, while file size depends on image detail and encoding quality as well. Check the saved JPEG bytes and use compression afterward if the destination also sets a KB limit.
