Faster website load times
Smaller images reduce page weight and improve Core Web Vitals scores.
02
Better SEO rankings
Google rewards fast-loading pages. Optimised images are one of the highest-impact improvements.
03
Meet upload size limits
Government portals, job applications and university forms require images under 50KB or 100KB. Compress to exact size
04
Protect your privacy
GPS, EXIF and camera data removed during compression. iPhone user? Convert HEIC to JPG

Why Do Photos Look Different After Uploading Them to a Website?
We uploaded the same three 12 megapixel photos to Facebook and X and measured what came back. Pixel count, bits per pixel and metadata all changed, in three separate steps. Here is what happened and how to upload so photos survive better.

How to Extract Text From an Image or Screenshot
OCR turns the letter shapes in an image into editable text, but accuracy depends almost entirely on the source image. Here is how resolution, skew, contrast and layout settings actually affect the result, and how to extract text from a screenshot in your browser with nothing uploaded.

How to Reduce Image Dimensions Without Losing Quality
Reducing pixel dimensions removes data rather than inventing it, so it should not cost quality. Here is why downscaled images actually look soft, the resampling algorithm that matters, and the one ordering mistake that compounds artifacts every time.

Why Is My PNG File So Large? How to Make It Smaller
A PNG is large for one of five specific reasons, wrong color depth, complex transparency, oversized dimensions, an unoptimized export, or a photo that should never have been a PNG. Here is how to tell which one applies to your file and fix it.
FAQ
Frequently asked questions
How much can I compress my images?
Savings depend on the source image, output format and quality settings. Some images are already optimized, and conversion can produce larger files. Compare the result before downloading. For strict size targets, use the dedicated target-size tools.
Can I compress an image to a specific file size like 50KB or 100KB?
Yes. ImgTweak has dedicated tools for 20KB, 50KB, 100KB, 200KB, 500KB and 1MB. There are also under-limit tools (under 50KB, under 100KB) for portal submissions. These are commonly required by government portals, job application systems and university forms.
What image formats does ImgTweak support?
The homepage accepts JPEG, PNG, WebP, AVIF, JPEG XL, HEIC, GIF, TIFF, BMP and SVG. It exports JPEG, PNG, WebP, AVIF or JPEG XL; HEIC is input only. SVG input is rasterized for conversion. Use SVG Optimizer to reduce SVG code while preserving vectors, and Compress GIF for animated GIF compression.
Can I convert HEIC photos to PNG or WebP?
Yes. Use the HEIC to PNG tool for lossless conversion with full transparency, or HEIC to WebP for smaller files than PNG. Both run entirely in your browser with no uploads required.
Can I process multiple images at once?
Yes. Select images, drop files or choose a folder. The workspace opens while files load progressively. Use Stop loading to skip remaining files, Cancel compression to pause unfinished work, Resume compression to continue, and Retry for failed images. Completed results are kept. Processing uses one or two compression jobs at a time depending on the device. Download completed images individually or as a ZIP.
Are there any file size or batch limits?
The homepage does not impose an arbitrary file-size or image-count limit. Large files and batches show warnings, but device memory and browser decoding capabilities still limit what can be processed. For very large folders, use smaller batches and download completed results regularly.
Are my images safe and private?
Image editing and compression happen locally in your browser. Your selected images are not sent to an image-processing server. Site analytics and advertising are separate from image processing; see the Privacy Policy for details.
Is ImgTweak really free?
Yes, 100% free with no hidden costs, no watermarks on exported images, and no feature limits. All processing runs in your browser so there are no server costs to pass on.
