Pertanyaan yang Sering Diajukan

How does the image resizer work?

Upload your image, set the target dimensions or pick a social media preset, and download the resized file in seconds. Everything runs in your browser — your photos never leave your device, so there is no upload wait and no privacy risk.

What image formats are supported?

You can upload PNG, JPG, JPEG, WebP, BMP, and GIF images. Output formats include PNG, JPG, and WebP with adjustable quality settings. PNG is ideal for graphics with transparency, JPG works best for photographs, and WebP offers smaller file sizes for web use.

Can I resize multiple images at once?

Ya! Fitur pemrosesan batch kami memungkinkan Anda mengunggah dan mengubah ukuran beberapa gambar secara bersamaan dengan dimensi dan pengaturan yang sama. Ini sangat berguna untuk menyiapkan foto produk, postingan media sosial, atau gambar portofolio yang memerlukan ukuran yang konsisten di seluruh kumpulan file.

Are there preset sizes for social media?

Yes, we include presets for popular platforms including Instagram Post (1080x1080), Facebook Cover (820x312), Twitter Header (1500x500), LinkedIn Banner (1584x396), YouTube Thumbnail (1280x720), and more. Presets are regularly updated to match each platform's current recommended dimensions.

Is my image data private and secure?

Absolutely. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to our servers or any third party. This client-side approach means your photos remain on your device at all times, making the tool safe for sensitive or personal images.

What is the maximum file size I can resize?

There is no strict file size limit since processing happens in your browser. However, very large images (over 50MB) may be slower depending on your device's processing power. For best performance, we recommend resizing images under 30MB on mobile devices and under 100MB on desktops.

Will resizing reduce my image quality?

Mengubah ukuran ke dimensi yang lebih kecil menjaga kualitas dengan baik karena algoritme mengambil sampel dari lebih banyak data piksel. Saat memperbesar gambar, diperkirakan akan terjadi penurunan kualitas karena interpolasi. Untuk keluaran JPG dan WebP, Anda dapat menyempurnakan kualitas dengan penggeser kami yang dapat disesuaikan untuk menyeimbangkan ukuran file dan kejelasan visual.

How do I resize an image without changing the aspect ratio?

Enable the aspect ratio lock toggle before entering your dimensions. When locked, changing the width automatically adjusts the height proportionally, and vice versa. This prevents your image from appearing stretched or squished, which is especially important for portraits and product photos.

Can I use this tool to reduce image file size for email or web?

Yes, resizing is one of the most effective ways to reduce file size. Lower the dimensions to your target display size, choose JPG or WebP as the output format, and adjust the quality slider downward. A 4000px photo resized to 1200px in JPG at 80% quality can shrink from several megabytes to under 200KB.

Does the resizer work on mobile phones and tablets?

Yes, the tool is fully responsive and works on any modern mobile browser including Safari on iOS and Chrome on Android. Processing happens on-device, so no app installation is needed. For very large images, a device with at least 3GB of RAM is recommended for smooth performance.
