Question 1

Can I maintain the aspect ratio?

Accepted Answer

Yes — lock the aspect ratio to resize proportionally, or unlock it for custom dimensions.

Question 2

Are there size presets?

Accepted Answer

Yes — common presets like 1920×1080, 1280×720, and social media sizes are available.

Question 3

Will resizing affect quality?

Accepted Answer

Enlarging an image may reduce sharpness. Downsizing generally preserves quality well.

Question 4

What is the best resize algorithm to use, and why does it matter?

Accepted Answer

For making images smaller, Lanczos filtering (the default) gives the sharpest result without aliasing artefacts on fine detail. For making images larger, bicubic gives a softer but cleaner result than nearest-neighbour. The tool uses both automatically depending on whether you are scaling up or down — you do not need to choose. The naive resampling that browsers and chat apps use silently in the background is much lower quality than what you get here.

Question 5

Will resizing an image stretch or distort it?

Accepted Answer

Not unless you turn off the aspect-ratio lock and enter mismatched width/height values. By default, changing the width automatically recalculates the height to keep the original ratio. If you specifically need to stretch or squash an image to non-proportional dimensions, click the lock icon to disable it.

Question 6

Can I upscale a low-resolution image to make it bigger?

Accepted Answer

Yes, but with a caveat: no algorithm can recover detail that was not in the original pixels. Bicubic upscaling produces clean, soft results — fine for moderate enlargements (say, 2x). Beyond that you start to see the underlying pixel structure. For aggressive upscaling of photos, dedicated AI upscalers do better, but for everyday "make this 800px image fit a 1200px slot" the built-in upscaler is more than adequate.

Question 7

Why does the tool offer fit-within-bounds in addition to exact dimensions?

Accepted Answer

Because most real-world resize jobs are "make it fit inside this area without stretching." Fit-within-bounds keeps the aspect ratio and shrinks the image only as much as needed to fit inside both the maximum width and maximum height you specify. Use exact dimensions when a destination system insists on a specific pixel size; use fit-within when you have an upper bound but the original ratio matters more than precise pixel counts.

Question 8

Can I resize a batch of images to the same dimensions in one go?

Accepted Answer

Yes — drop multiple files at once and the tool applies the same resize settings to each. Each output downloads as a separate file with a "-resized" suffix so the originals are not overwritten. The same algorithm runs on every file regardless of input format, so you can mix JPEGs and PNGs in one batch.

Question 9

Does resizing an image lose quality?

Accepted Answer

Downsampling (making smaller) is lossy in the sense that pixels are discarded — but the Lanczos filter discards them intelligently, so the result usually looks crisper than the original viewed at the same display size. Upsampling (making larger) does not invent detail. The output format also matters: JPEG re-encoding adds a small amount of compression loss, while PNG output is lossless after the resize.

Question 10

How small can I make an image with this tool?

Accepted Answer

There is no enforced minimum. The tool accepts any positive width and height. In practice, anything below about 32 pixels stops being useful as a recognisable image — for icons, work in vector formats instead.

Question 11

Does resizing strip the EXIF metadata in my photos?

Accepted Answer

By default, EXIF (camera info, GPS, date) is preserved. If you want to strip it — for privacy when sharing publicly — use Compress Image afterwards with the metadata-strip option, or pick the "web" preset on this tool which removes EXIF in addition to resizing.
