Resize an image

Set an exact width and height, or pick the size a form is asking for. The resizing runs in this tab, so your photos never leave your device.

How to resize an image

STEP 1

Choose images

Add JPG, PNG or WebP images and choose custom dimensions or a preset.

STEP 2

Set the controls

Keep the shape lock on for proportional resizing; each source keeps its own aspect ratio.

STEP 3

Compare the result

For exact width and height, crop to that ratio first, then disable the lock and set both numbers.

STEP 4

Save and inspect

Resize and check each result's displayed pixel dimensions before saving.

Resizing, cropping and squashing are not the same thing

Illustrative example: a 1600 × 1200 picture resized proportionally to width 800 becomes 800 × 600. Forcing 800 × 800 stretches it. Crop square first if a square is required. Locked mixed-shape batches share a width, not necessarily a height.

Presets include 600 × 600, 413 × 531, 1920 × 1080, 1080 × 1080 and 1080 × 1920. These are convenient dimensions, not an acceptance guarantee. The tool re-exports images and cannot create missing detail when enlarging a small source.

Questions

Does this guarantee an upload KB limit?

No. Check dimensions here, then use Compress to a size if the destination separately limits file size.

Can I use HEIC?

Use the dedicated HEIC to JPG tool if this browser cannot decode a HEIC here.

Are my originals changed or uploaded?

No. Processing happens on this device and creates separate downloads. Keep originals until you have checked the saved files.

Pixels, presets and shape

Set a width and height in pixels, up to 12000, or pick a preset: passport photo, visa photo, Full HD, a social square or a story size. With Keep the original shape switched on, you give the width and the height follows each picture's own proportions, so nothing is squashed.

With it switched off, or when you pick a preset, the exact width and height are forced. That stretches or squashes a picture that is a different shape, because the tool resizes rather than crops. If you need a particular shape, use Crop & rotate first and then resize.

Tips

Making an image bigger does not add detail, it only enlarges what is there, so a small picture will look soft. The same size is applied to every file in a batch.

The result keeps the format of the original, with PNG and WebP staying as they are and other types saved as JPG. The quality slider, 40 to 98 percent, only matters for JPG and WebP. To change the format as well, use Convert format.
