How to Use Pressify
Drag and drop your images onto the upload area, or click it to pick files. You can add up to 20
images at once - JPG, PNG, WebP and GIF are all supported.
Choose your output format, scale and quality, then hit Process. Each result appears
with a before/after preview. Download images individually or grab them all as a ZIP.
Need a specific filename? Use the File Name options to add a custom prefix, suffix, or auto-number
your images.
Use Cases, Best Settings & Common Mistakes
Use cases: compress product photos for ecommerce, optimize blog images for faster pages, and
bulk-prepare social media assets.
Best settings: start with WebP at 75-85 quality, keep PNG for transparency/UI, and resize oversized
uploads before final export.
Common mistakes: exporting logos as JPG, over-compressing below 60 quality, and forgetting to strip
EXIF before public sharing.
Frequently asked questions
Why Local Processing Matters
Most online image tools upload your images to their servers for
processing. This poses a privacy risk if your images contain sensitive personal information or
confidential data.
Pressify is different. We bring the power of image manipulation directly
into your web browser. When you compress, resize, or convert images on Pressify, the actual
processing happens using the processor on your device. Your files are never uploaded, stored, or
viewed by anyone else.
Lossy vs. Lossless Compression
Lossy compression (used by JPEG and WebP) discards
some image data permanently. At high quality settings the difference is invisible; at lower settings
you trade some detail for a dramatically smaller file.
Lossless compression
(PNG, GIF) reduces size without losing any data - every pixel in the output is identical to the
original. This is ideal for logos, icons and images with sharp text.
Which format should I choose?
JPG - best for photos. Great compression at 70-85%
quality with nearly imperceptible loss. Avoid for images with
transparency.
PNG - best for graphics, screenshots and images requiring
transparency. Larger files, but perfectly sharp.
WebP - Google's modern
format. Offers better compression than JPG and PNG with support for transparency. Supported by all
modern browsers.
GIF - limited to 256 colors. Legacy format mostly used for
simple animations.
What is EXIF metadata?
EXIF data is hidden information embedded in image files by cameras
and smartphones: GPS coordinates, device model, lens settings, timestamps and more. When you share
photos online this data travels with the image. Pressify's Remove metadata option strips
all EXIF data, protecting your privacy with zero quality loss.
What quality setting should I use?
For web images 75-85% quality is the sweet spot - visually
identical to the original but 40-70% smaller. For print or archival purposes use 90-95%. Going below
60% produces visible artifacts and is rarely worth it.
Can I compress images without losing quality?
Yes. Use PNG or GIF with lossless workflows when quality must stay
exact. If you use JPG or WebP, higher quality values reduce visible loss while still shrinking file
size.
How much can image compression reduce file size?
Typical savings are around 30% to 80%, depending on the source
image, selected format, target quality, and resize settings.
Is Pressify free and private?
Yes. Pressify is free to use and processes files locally in your
browser. No account is required and your images are not uploaded to a server.
What is the best format for website performance?
WebP is usually the best balance for web performance and quality.
JPG remains a safe choice for photos, while PNG is best for graphics and transparency when quality
is
critical.
Can I resize and rename images in bulk?
Yes. Pressify supports batch resize, conversion, compression, and
custom naming with prefix, suffix, and auto-numbering.
Can I remove the background from an image?
Yes. Pressify includes an AI-powered background removal tool that runs entirely inside your browser using ONNX Runtime. No image is ever uploaded to a server.
What is the Seamless Texture Checker?
Seamless Texture Checker is a built-in tool that tiles your image across a full-screen panel so you can verify whether it repeats without visible seams.
