Kompres PNG Online

What Kompres PNG does

Image compression makes a file smaller so it uploads faster, loads quicker on a web page and fits the size limits of forms, email and chat apps. The picture is decoded to pixels and saved again with stronger compression.

JPG files are encoded with MozJPEG, which produces smaller files than standard JPG encoders at the same quality. PNG files are reduced to a palette of at most 256 colors, and the PNG Compressor can also optimize them without changing any pixel. If the result is not smaller and the format stays the same, you get the original file back.

Cara menggunakan Kompres PNG

1. Letakkan file yang ingin Anda perkecil.
2. Pilih tingkat kompresi, atau gunakan pengaturan yang direkomendasikan.
3. Klik Kompres dan bandingkan ukuran file lama dan baru.
4. Unduh file yang sudah lebih kecil.

When to use Kompres PNG

• Shrink phone photos of several megabytes before attaching them to an email or uploading them to a form with a size limit.
• Reduce product images and blog photos so web pages load faster and score better in page speed tests.
• Make PNG screenshots smaller for documentation, support tickets and chat messages while keeping the text easy to read.
• Prepare a batch of images for a website by limiting all of them to a maximum width, such as 1920 pixels.

Settings explained

Output format

Shown in the Image Compressor. Same as input keeps the format. Choosing WEBP or AVIF instead usually gives a much smaller file than JPG or PNG at similar visual quality.

Quality

Sets the compression strength for JPG, WEBP and AVIF, from 10 to 100. The default of 75 is a good balance; 60 to 70 gives smaller files for web use, and 85 or more suits printing.

Compression mode

Shown in the PNG Compressor. Smaller (lossy) reduces the image to a limited color palette and gives the biggest savings. Lossless keeps every pixel exactly and only optimizes how the data is stored.

Colors

Shown in Smaller (lossy) mode. Sets the palette size from 8 to 256 colors; the default is 256. Screenshots and graphics often look the same at 64 to 128 colors, while photos need 256.

Max width (0 = keep)

Scales down images that are wider than this number of pixels, keeping the aspect ratio. Narrower images are not enlarged. For web pages, 1600 to 2000 pixels is usually enough; 0 keeps the original size.

Apa itu PNG?

PNG (Portable Network Graphics) adalah format gambar yang diperkenalkan oleh W3C pada tahun 1996. Format ini menggunakan kompresi lossless dan mendukung transparansi. File menggunakan ekstensi .png.

PNG was created in the mid-1990s as a free replacement for GIF, whose compression method was covered by patents at the time. It applies a filtering step and then compresses pixels with the DEFLATE algorithm, so every pixel is kept exactly. It supports full color, grayscale, palette images and a full alpha channel for smooth transparency.

PNG is the right choice for screenshots, logos, icons, diagrams, user interface graphics and any image with sharp edges, text or flat colors. It is also a safe format for images that need transparent backgrounds or will be edited again.

Because PNG is lossless, photos saved as PNG are often several times larger than the same photo saved as JPG or WebP. PNG has no lossy mode, and a standard PNG file cannot store animation.

PNG opens in every modern web browser, on Windows, macOS, Linux, Android and iOS, and in practically all image viewers, image editors, office suites and design tools. It is one of the most widely supported image formats.

Mengapa memakai Kompres PNG dari FansBond

Sebagian besar konverter online mengunggah file Anda ke server mereka. Kompres PNG dari FansBond justru memproses semuanya di dalam browser Anda, menggunakan WebAssembly dan API browser modern. File Anda tetap berada di perangkat, sehingga lebih aman untuk foto pribadi, kontrak, dan karya yang belum dirilis, dan sering kali lebih cepat karena tidak ada yang perlu diunggah atau diunduh.

Tidak ada antrean, tidak ada watermark, dan tidak perlu akun. Setelah halaman dimuat, alat ini tetap berfungsi bahkan dengan koneksi yang lambat.

Tips for the best result

• Reducing the width often saves more than lowering the quality. A 4000-pixel phone photo shown at 1200 pixels wastes most of its data.
• Avoid compressing the same JPG again and again. Each save loses a little more detail, so always start from the original file.
• For photos saved as PNG, converting to JPG, WEBP or AVIF usually saves far more than any PNG setting, as long as you do not need transparency.
• Saving as JPG fills transparent areas with white. Keep PNG, WEBP or AVIF output for logos and graphics with a transparent background.

How Kompres PNG works in your browser

When you add an image, the browser decodes it into raw pixels on your device. HEIC photos are decoded with a browser build of libheif, and AVIF with the libavif decoder. The pixels are then processed on an HTML canvas and encoded again in the format you picked.

JPG, PNG and WebP are encoded with your browser's built-in encoders, and AVIF with libavif compiled to WebAssembly. The compressors add MozJPEG for smaller JPG files and OxiPNG for lossless PNG optimization. Because everything runs locally, the speed depends on your device rather than on a server queue.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Kompres PNG works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
