How do I make my signature or photo under 20KB?

Upload your file to ResizeInKB, set the target size slider to 20 KB (pre-set), and the app will instantly recalculate compression quality to deliver a file strictly under 20KB.

Will my 20KB image become blurry?

ResizeInKB uses smart adaptive downscaling. If the original photo is too large, it automatically adjusts pixel dimensions proportionally so the compressed 20KB photo remains crisp and readable.

Can I convert a 5MB phone camera photo to 50KB?

Yes! ResizeInKB can take multi-megapixel camera photos (5MB - 20MB) and downscale both quality and dimensions to fit under 50KB seamlessly.

How do I make sure text on scanned certificates remains readable at 100KB?

ResizeInKB maintains high pixel density while adjusting lossy compression matrices, ensuring high contrast text remains sharp even at 100KB.

What is the standard passport photo dimension in pixels?

The most common passport photo standard is 350 x 450 pixels (aspect ratio 7:9, corresponding to 3.5 cm x 4.5 cm).

Will PNG compression remove my transparent background?

No, transparent PNG channels are preserved during compression.

Does JPEG compression change original file metadata?

ResizeInKB strips unnecessary heavy EXIF metadata during compression to reduce extra kilobytes automatically.

Why should I convert my website photos to WEBP?

WEBP files load up to 3x faster than traditional JPEGs, dramatically reducing bandwidth usage and page loading time.

Are my uploaded photos saved on any database?

No! We do not host or store any user images. All resizing and compression happens on your own computer or smartphone GPU/CPU.

Why should I remove EXIF & GPS data before posting photos online?

GPS location tags reveal the exact physical location where a photo was captured, which can compromise personal privacy if posted on social media or forums.

Are my photos or brand logos uploaded to any server?

No! All image rendering and logo stamping happens entirely on your device using HTML5 Canvas. Your photos and private brand logos never leave your computer or phone.

Can I watermark transparent PNG images without losing transparency?

Yes, select PNG output format and transparent backgrounds will be fully preserved during watermarking.

Is my photo sent to any AI cloud server?

No! All image rendering and pixelation happens entirely inside your device's browser memory. Your documents never leave your phone or PC.

Are my photos uploaded to any server when converting to PDF?

No! All PDF rendering happens completely inside your device's browser memory using jsPDF. Your images remain 100% private.

Can I convert multiple photos into one single PDF?

Yes, you can upload as many images as you like and reorder them before exporting them into a multi-page PDF document.

Are my document images uploaded to any server during OCR?

No! The entire Optical Character Recognition runs locally inside your web browser using WebAssembly technology. Your files never leave your device.

What languages are supported for image text extraction?

We support over 15 languages including English, Hindi, Spanish, French, German, Portuguese, Russian, Arabic, Chinese, Japanese, Korean, and Indian regional languages like Marathi, Gujarati, Bengali, Tamil, and Telugu.
