Frequently Asked Questions

No — never. Every operation (resize, compress, crop, filter, rotate, convert) runs entirely inside your browser using the HTML5 Canvas and OffscreenCanvas APIs. Your images are never transmitted anywhere. You can verify this by turning off Wi-Fi after loading the page; every tool keeps working because nothing needs the network.

Yes. Because processing happens locally on your device, your passport photos, ID cards, and other sensitive documents never leave your browser. This makes PixelFix Pro safer than editors that require a server upload.

No account is required. Just open the page, drop in your image, and start editing. No email, no password, no sign-up wall.

Yes. All core editing tools are free to use with no hidden paywalls, no trial periods, and no artificial file-size limits. We display non-intrusive ads to cover hosting costs.

PixelFix Pro works in all modern browsers that support OffscreenCanvas and createImageBitmap: Chrome, Edge, Firefox, and Safari 16.4+. We recommend keeping your browser updated for the best performance.

Click the Smart Compress button in the Quick Fixes panel. Move the target size slider to 2.0 MB, then click Compress. The tool re-encodes your image as JPEG at decreasing quality levels until the file is under your target — typically in just a few seconds.

Use the same Smart Compress tool. Set the target size slider to 0.1 MB (100KB) or 0.5 MB (500KB), then click Compress. The iterative algorithm will find the highest quality setting that fits your exact limit.

Smart Compress is designed for exactly this. It uses iterative JPEG quality reduction over multiple passes, always keeping quality as high as possible while meeting your size target. For best results, start with the highest quality setting and let the tool optimize downward.

Smart Compress reduces file size by adjusting JPEG quality — it does not change pixel dimensions. If you also want to make the image physically smaller (e.g., 1080px wide), use the Resize tool first, then compress.

JPEG compression discards image data, and if the target size is very small relative to the original dimensions, some quality loss is unavoidable. For documents and ID photos, resize to the exact pixel dimensions required first, then compress. For photos, try reducing dimensions by 20–30% before compressing.

iPhone photos default to HEIC format. Simply drag your HEIC file onto PixelFix Pro or click browse and select it. The tool converts it to JPEG automatically on load — no server upload, no iTunes, no extra apps needed.

Yes. The conversion runs through the heic2any library entirely in your browser, re-encoding at 92% quality by default. The resulting JPEG is visually identical to the original HEIC at typical viewing sizes. For print or archival, keep the original HEIC if possible.

Yes. Load your PNG image, then in the Export & Download section select 'WebP — Smallest size' from the format dropdown before downloading. WebP files are typically 30–50% smaller than PNGs at comparable quality.

You can load JPG, PNG, WebP, HEIC, HEIF, BMP, GIF, and TIFF. For download, you can export to JPEG, PNG, or WebP. iPhone HEIC photos convert to JPEG automatically.

Currently, PixelFix Pro handles one file at a time per tab. For batch conversion, open multiple tabs or use the Images → PDF tool to upload multiple HEIC files, export as PDF, then re-save each page as JPG from a PDF viewer.

Select 'Instagram Square Feed (1080×1080)' from the Resize & Smart Presets dropdown. The width and height fields auto-fill to 1080×1080, and the aspect lock ensures your image won't stretch. Click Resize, then download.

Stories and TikTok videos use a 9:16 vertical format. Select 'Instagram / TikTok Story (1080×1920)' from the preset dropdown. For Instagram portrait posts, use 1080×1350 (4:5 ratio) for maximum feed real estate.

Amazon requires a minimum of 1000×1000 pixels for the zoom feature. The 2026 recommended size is 1600×1600 ('Amazon Zoom' preset) or 2048×2048 ('Shopify / Amazon Pro') for future-proofing. All are available in the preset dropdown.

Select 'US Passport Print (600×600 @ 2×2 in)' from the ID & Passport Photos preset group. Then use the crop tool with a 1:1 aspect ratio to frame the head correctly. The final image is exactly 600×600 pixels at 300 DPI when printed at 2×2 inches.

Click Draw Crop, then select the desired ratio from the Crop & Transform dropdown (1:1 Square or 16:9 Widescreen). The crop box constrains to that ratio automatically. Drag the corners to adjust size, then click Apply.

US Visa and USCIS require 413×531 pixels. Select 'US Visa / USCIS (413×531)' from the preset dropdown. Crop to 1:1 for the head-and-shoulders framing, then download at exact dimensions.

Type your watermark text in the Watermark field (e.g., '© Your Name 2026'), pick a position (bottom-right is standard), adjust opacity with the slider, then click Add Watermark. The text is rendered directly onto the image and included in the download.

Use the rotate buttons for 90° clockwise or counterclockwise, or the Flip H / Flip V buttons for mirror effects. These are in the Crop & Transform section. All transforms are non-destructive until you apply them.

Yes. Copy any image (screenshot, photo from another site, etc.) and press Ctrl+V (or Cmd+V on Mac) anywhere on the page. It loads directly into the editor without needing to save the file first.

Click the 'Before / After' button in the canvas toolbar. A vertical divider appears — drag it left and right to compare your original image against the edited version in real time. Exit comparison mode by clicking the Exit button or toggling Before/After off.

Yes. PixelFix Pro saves up to 20 history snapshots. Use the Undo and Redo buttons in the toolbar, or press Ctrl+Z to undo and Ctrl+Y to redo. You can also click Reset to return to the original image at any time.

The brightness, contrast, saturation, and hue sliders preview live using fast CSS filters so you can experiment instantly. To make the change permanent and included in the download, click 'Apply Changes' after adjusting the sliders. (The Download button also automatically bakes in any unapplied preview.)

There is no artificial file-size limit imposed by us. Very large files (over ~50MB) are constrained by your device's available browser memory. Most everyday photos under 20MB process instantly. If a file is extremely large, try resizing it to smaller dimensions first.

Pixel-level operations like sharpening, blur, and vignette examine every pixel and its neighbors using convolution. For a 6000×4000 DSLR photo, this can take 1–2 seconds on a typical laptop. Resizing down first, or using effects sparingly, keeps things fast.

Yes. The editor is fully responsive and works on iPhone, Android, and tablets. Touch gestures are supported for crop drawing. Use Chrome or Safari (latest version) for the best experience, and keep the tab active while processing large images.

Smart Compress iteratively re-encodes your image as JPEG at decreasing quality levels — up to 10 passes — until the file size falls at or below your target. Each pass reduces quality slightly, so the result is always the highest possible quality within your size limit.

The image editor handles one image per tab for quality and performance reasons. For batch tasks, use the PDF Tools page to merge multiple images into one PDF, or open multiple tabs and apply the same preset to each file manually.
